Dr. Osner is really nice and very helpful. He is relatively new at teaching, but he knows his organic chemistry well. There is no homework that you need to turn in, but there are assigned problems that he highly recommends. Also midterms and a comprehensive final, but he drops the lowest midterm. The class is very fast faced to be prepared!!!

fairly new teacher, but very good. his notes come directly from the book, but he clarifies and explains better in lectures. no homework, just optional practice problems. he emails practice exam questions and his exams match perfectly.

He might be new at teaching, but he know the stuff and he matches perfect his notes with the books. I have never seen a helpful professor as he is. He gives you everything that will be on the test, he makes one hour review besides the lecture hours. He is a nice guy and a really helpful professor.

Very helpful, very clear, and SO FUNNY. I love his lectures. He will randomly talk about current events. He keeps me interested in orgo. I'm taking him again next semester. read the chapter before going to lecture. MAKE SURE TO DO THE PROBS AND PRACTICE TESTS REPEATEDLY!

Very knowledgable and funny in a dorky way. His notes do match the textbook and just like any other orgo class, it is fast paced. Be prepared to dedicate many hours into Orgo. He's also very helpful and in my opinion boyishly handsome. Great guy, great teacher. Relatively new but you won't regret taking his class.

Not only is he sexy but he is very helpful and gets me motivated to go to class in the morning. Do the practice test they help a lot on what areas to focus studying on.

He is always willing to help in office hours. His exams have been very close to his practice tests (DO THEM!). Discussions are helpful too because he gives us test-like problems. Some days I feel like I am wasting my time in class because he follows the book that well (yes, that is a criticism and a compliment). I wish he used colored chalk.

Osner is an awesome guy. He looks like he used to be a drummer for a punk bad. He is very clear and follows the book. His exams aren't too bad but the grading curve can make what seems like a good score an average grade, which sucks. Overall I liked him and I am signed up for his section next year. Take!

He's dope. Dont miss class. Do the homework problems and practice exams & you'll be golden. Its organic, put the time in & don't be a lazy schmuck.

Osner is extremely attractive and a great, great teacher. Orgo is hard but he genuinely wants you to do well. Go to class, take good notes, do as many of the homework problems as you can, study study study. He answers questions and is a really fun professor. Tests are difficult, but the curve is helpful. Would highly recommend.

He is probably the best orgo professor out there. He is funny, helpful, and knows his stuff very well. He makes orgo look a lot easier. He goes out of his way to help you and wants you to do well. His jokes make the class interesting. He is one of the best professors you will ever have. He is kinda young and new to Loyola. #Respectforosner

Dr. Osner, yeaaaaaaah budddy. He's got moxie.

Dr.Osner is a great professor. He is extremely FAIR, nice, and helpful(a quality not many science profs at loyola have).If you do your work, you will get an A or at least a B. He rewards you for ur effort & work. He is really funny and makes organic chemistry fun and doable.I have been at Loyola for 2 years, and he is is the best professor so far.

Osner somehow makes organic chemistry enjoyable. Great lecturer. He's crystal clear and follows the book very closely. He's also approachable and helpful both in and out of class. He wants students to succeed, and if you put in the time to learn the material (this is still orgo, so you do have to work) you will do well.

Summer with Osner for CHEM 101 made me actually like Chemistry. His lectures are very clear, though he tends to write quite an amount. MasteringChemistry homework is part of the grade BUT 20 points goes toward extra credit if you finish all the assignments. Plus he's extremely attractive. Sort of like a Joseph-Gordon Levitt nerd-like quality.

GREAT professor!! Charismatic, funny, and intelligent. TAKE DR. OSNER! He is a great professor and loves what he does. Tests are straight forward, he has review sessions before each exam. 3 exams; drops the lowest. 1 final. Uses Mastering Chemistry. No other points.

He's okay. 90% of his exam questions are fairly straightforward and then the last 10% or so are very hard.

Awesome professor! His class can be a little boring because all he does is lecture and write everything on the board for 50 mins. His tests are 25 multiple choice 4 pts each but if you show work he gives partial credit. Exam was pretty straightforward with 50 multiple choice. He wants to see you succeed. Take him if you have the chance!

As a non-chem major, Dr. Osner is a great choice for chemistry professors at Loyola. You can tell he has a passion for his work and wants his students to do well. Drops the lowest exam, final is cumulative, 25 multiple choice at 4 pts each. Lecture can be boring at times, but overall he's great.

BEST PROFESSOR EVER! REALLY COOL GUY! You will learn a lot in his class, he is very nice and relatable. Go to class, take good notes, and ask questions.

For being a subject I hate, he does a great job at making it go as smoothly as possible. And for being a large lecture, he does a very good job at learning most of the students names. Definitely recommend him!

Hate the subject, love the prof. He's a very good professor, but he is definitely not a hand holder. Will be a bit of a shocker if you're fresh out of high school. He doesn't tell you when your homework is due, and it's not always due on the same day so stay on top of it. You need to study and put in a bit of work, but a good grade is attainable.

Really helpful, very clear. Made organic chemistry bearable. Very highly recommended. :)

Dr. Osner can easily described as a bro. He is just a fun guy to talk to and a great teacher. During his discussions, he will give out practice problems that you can work on as a group. Then, he'll go over them in class to make sure everyone understands them. His step by step review of each problem helped me get an A. I highly recommend him.

Great chemistry professor no matter how interested you maybe in the subject. No need to read the book, but be prepared to take notes the entire time in class. His exams are doable and I've heard he is very helpful during office hours if you need extra help.

This guy is the best. You have to come to class because all of the notes are written on the board for you to copy. Tests were very fair and there was always enough time to finish them. There was a LOT of extra credit as well. Certainly one of the best if not the best chemistry teacher

Amazing teacher; take him!! Lectures are so easy to follow. Discussion is extremely helpful (mandatory attendance to discussion). Very intelligent and funny. Exams are very fair, not easy though. He is very sensible. Do Mastering Chemistry, study a lot for exams, attend every class and you can definitely get a B at least. Drops lowest exam!

Crystal clear professor. His lectures were easy to learn from. The tests, although difficult, were very fair. Always available for extra help. There was a very small amount of extra credit to make up for the fact that there was no curve. Learned a lot but I felt he became sort of full of himself toward the end. The clearest chem teacher at Loyola.

He is super helpful when you ask him questions. His tests are pretty straight forward and he warns you what the longer free response questions will be. He explains why the reactions work instead of just showing you the reactions. His tests are not impossible if you are willing to put in the work. He is very approachable and helpful

The best chemistry prof out there, really takes time to explain everything. Gives a study guide and practice test before all exams so you can really prepare. Plus he curves generously according to how the class does.

Osner is great! I had him freshmen year for Chem 101 and this past semester for Organic Chem. His lectures are very clear, and he genuinely wants everyone to do well. He gives three tests and a final. The lowest test score is dropped. He also gives extra points for attending all the discussions. Writes notes on board. Overall very good. Take him :)

Osner is by far a great Organic Chem Lecturer. Obviously the content is difficult but he makes it clear in his lectures. Put in the work he asks for and you'll be rewarded.

Firstoff, he's hot. But anyway, I loved his orgo class. He tells you exactly which mechanisms you need to know for each test so you don't get blindsided at all. He will also usually tell you what kind of questions the long answers will be. He's hilarious and also his office hours are great practice since he works out problems for everyone there.

Amazing professor! Writes all his notes on the board so you just have to copy. Discussions are mandatory but he gives 8 points extra credit if you attend all of them. Mastering chem is easy and he only counts 50 out of the 60 points. The rest is extra credit. Super generous grading scale too. If you want an easy A and a good professor, take him!

Dr. Osner is a great professor, and is one of the best Chemistry professors at Loyola. Although he offers a lot of help, his exams aren't a whole lot easy. To get that easy A, you will need to still study and put in a lot of effort. Going to his office hours will help as well. Overall, he is very clear and helpful. And he's hot!

Wouldn't say it's an easy A, but you can get a good grade if you work hard and practice. His notes are super clear and his tests only cover stuff covered beforehand in class. The greatest teacher in the department and he's an awesome guy, really easy to relate to and ask for help. You will learn a lot! On top of that, he's my mcm and im straight.

Dr. Osner is a fantastic teacher! He takes time to write out all his notes on the board. Is always down to help students and answer questions. Have to read the book, and if you miss a class, you're screwed. His tests may be a bit difficult, but he offers XC for going to all discussions (which are very helpful). I would definitely take him again.

Dr. Osner is really funny and a great teacher! His lectures are very clear and is very helpful when studying for the test. There is mastering chemistry and the three tests are about 20 Q's and 5 free response. Dr. Osner drops one of the tests and the final is just like his other tests. If I don't get him for second semester I'll cry :'(

Hilarious, nice guy. 3 tests w lowest dropped, 1 cumulative final, online homework, and discussion makes your grade. He gives a lot of extra credit. Very helpful and clear cut. His tests are kind of difficult but doable. He writes all his notes on the board clearly. Absolutely love him. Taking him next semester in fact. MUST TAKE.

Dr. Osner is a gem of the Loyola staff. He is one of the greatest chemistry professors you can take here. He has 3 exams and drops your lowest grade. Lecture's are all hand written on the board by him so it is very easy to keep up. I would HIGHLY recommend taking Osner!!

Cool guy, cares about his students.

Osner is phenomenal. The lectures were long, but he makes them interesting and fun. Very relaxed, but still serious about the subject. Orgo Chem is his forte. I highly recommend. Discussions are well designed. Study, study, study!!!! It's orgo and supposed to be difficult!

Dr. Osner is one of the best professors I have ever had at Loyola! He's always there to help you out and he really knows his stuff. Organic Chemistry is a challenging class in general but it was a little bit more bearable with him.

One of my favorite professors!!! As long as you pay attention in class, understand the material/concepts, do the mastering assignments, and do the practice exam, you'll do well. Personally, I loved his teaching style and I liked when he would incorporate real world examples into his lectures.

Osner is perhaps a little overrated, but is a good professor (especially compared to others). He drops the lowest of three tests, and is fairly clear in lecture, but could be so much clearer (I came in knowing chemistry and the way he explains some things is deliberately more complex than it has to be). Overall easy to do well if you put in effort.

Osner is my favorite!! Although his lectures are long, he writes every thing he says on the board and he knows what he is talking about. His notes are easy to understand. Tests are based off discussion worksheets and the practie tests he posts prior to the test. Take him!

Very easy to understand during lecture. He takes off a lot of Mastering points, however, he also drops your lowest test and gives extra credit if you go to every discussion. Tests weren't necessarily a cake walk, but they were fair for the most part. If you put in the work, you will get an A. Do not buy the textbook! We didn't use it once.

TAKE! TAKE! TAKE! Don't pass the opportunity to have one of the funniest and best professors at Loyola. Put in work and you will get an A! There are a lot of extra credit points at the end and just make sure to do the Mastering Chemistry homework.

He's very clear during lectures. His lectures can be long and you should expect them to go the entire time. Discussion is easy and is mostly just good practice for the tests. He usually gives out similar questions to what will be on the test in discussion. His lectures follow the book super closely, rereading the book after lecture helps a lot.

Osner is a great teacher, lectures are extremely clear. His discussions give you a good look at what the tests are like and if you go to his office hours, he's very helpful. Reading the book is not really necessary as he coves the material he tests on well in class. That being said, if you want a good grade, you have to attend the classes.

Dr. Osner is an incredibly great & clear instructor. His lectures are almost word for word from the textbook. His lectures couldn't be clearer. Attendance in discussion or lecture are NOT mandatory but don't expect 2 pass w/out it. drops lowest of 3 midterm grades. Mastering Chem, only downfall. GO TO OFFICE HOURS he is incredibly helpful! EC poss.

While Dr. Osner is super funny, his lectures were long and it was hard to focus. Also, his Mastering Chemistry assignments were extremely difficult and didn't really pertain to what we were learning in class. His tests are also pretty difficult. But he's more than willing to help if you ask for it, and his notes are pretty easy to follow.

Best professor ever. If you have a chance to take this guy do it.

Amazing guy, talks about his cats a lot. Grading scale makes life less difficult. Go to discussion and class if you want to do well.

Dr. Osner is great. His grading scale is generous and exams are not too difficult if you study the material and practice. It is not an easy class but an A is doable if you work hard and study. He drops an exam and a quiz. Make sure you attend all the discussions as this helps w/ the material. Put in the work and you'll get the grade you want.

Lectures are taken straight from the book, but the book can be helpful for topics that are glossed over in lecture. Exams are fair and test only on covered material, but averages hovered around a B/B-, sometimes at a C+. Practice problems are optional but helpful, though problems from discussions are more helpful with preparing for his exams.

Osner is one of the better Orgo teachers. He gives quizzes and you get discussion points with exams but his grading scale is so lenient. It really gets easier to get a B- to a C- in this class with ease. He understands it is a tough class and is a very good professor. He explains stuff well and is passionate.

I loved Dr. Osner's lectures. Everything was broken down into very clear pieces and he stops lecture to answer questions. His tests are challenging but very fair. You have to study a lot and work fast, but they are very doable. Also, do the mastering chem assignments. he chooses the difficult questions and they really help your understanding

I took Dr. Osner for CHEM101, and the difficulty of the class has changed significantly. He's probably still the lesser of all evils, but buckle up kiddos, because this is going to be a wild ride. Invest in Chegg and/or the answer manual for Mastering. The final is cumulative over all of gen chem, so don't count on it to save your grade.

Hard class, but definitely doable if you have the mindset to work hard and study. If you do well on the mastering Chem you will get xtra cr at the end which helps out. If you can most of the mastering Chem problems and understand them you will be fine. Just be prepared to put in the time and utilize office hours because he can be very helpful then

Dr. Osner is the best Chem 101 professor. He writes all his notes on the board, so lectures move at a really steady pace. While there is no attendance at lecture or discussion, I would highly recommend going because some of the book topics arent necessary. Hes really approachable if you ever need help too.

As expected, Orgo is hard. But Osner makes it bearable because he is funny and nice and really cares about his students. Don't be afraid to go to office hours, it's really helpful if you don't understand something. Best Chem professor I've ever had

Very helpful lectures. He is very good at clarifying difficult topics and makes a dull subject enjoyable and relevant.

Dr. Osner is the BEST chem prof! everyone knows how messed up the chem dept is but Dr. O not only CARES that you are learning, but he is also funny and relatable. He actually makes what seems like a scary subject fun and interesting and you will want to learn. Work hard in his class and go to office hours and will definitely pay off!

everyone says he's an easy A, he's not. Yes, definitely the best choice out of the others but chem is not an easy class. Maybe his first test was a joke, but his test format makes it tough and quizzes are graded hard. Need to put In the work but a good grade is possible. Final was really rough

Accessible. If you have had Chem before he is a solid choice, if not, I don't think he gives enough example problems. His HW is on Aleks which is similar to Khan Academy- 10% of grade. He grades his quizzes (15%) hard and they are hand written. You really have to budget your time with his tests, they are 25 MC but very hard and if you miss 3 Q B+

Osner is the best! I had him for gen chem as well as organic and he is by far my favorite professor. I am TERRIBLE at chemistry and his class was really hard, but if you go into his office hours he really looks out for you! He's super clear one-on-one and cares that his students understand the material. He's also pretty funny and quirky, good dude

I took the chem 102 that he co taught with Helquist and he is the only reason I survived in this class. His lectures are very easy to follow and understand and he is willing to help you outside of class! Has a great sense of humor.

Dr. Osner is the shining gem of Loyola's horrible chemistry department. Lectures are clear and tell you everything you need to know. If you do the Aleks homework and read the textbook, the getting an A is pretty easy. His chem 102 class is definitely harder though.

Dr. Osner is probably the best organic chemistry professor as far as explaining the material goes. Watch out for his tests though, they're pretty hard.

Take this man! He cares about his students and is always winning to help the students out. Exams are a tricky but as long you study the material and remember stuff from orgo 1, then you will blow right by it. He lets you use a cheat sheet!!!!!

Great professor. Cares about all his students. Go to office hours with questions, he easily clears things up. This semester he did post videos of his lectures online for students to watch again if needed. Uses ALEKS and has problems from the textbook (free response on the test!!!). Exams are hard but if you go to class and study it's not that bad.

I failed chemistry in highschool. I got an A in this class. He is an amazing professor who is accessible outside of class and willing to work through problems with you, even explaining things in different ways until you understand the material. His tests are not difficult if you 1) read the book 2) rewatch hard lectures on panopto 3) do problems

Osner really is an amazing chemistry professor. Chemistry is hard but he makes it bearable by making his lectures easy to follow, being accessible outside of class, and truly caring. If you're willing to put in the work, you will succeed. There is no easy A professor in chemistry because it isn't an easy A subject. However, it is doable with osner.

Dr. Osner is an incredible professor. I was under the impression he would be an "easy A" but he's not, he is just a really good teacher. He jokes with the class but still covers all the material you need to know. Final is harder than tests, I had a solid A before, but I would recommend his class nonetheless. Phenomenal lecturer, I'd take him again

Osner's class taught me how to study. Exam's weren't easy, but he gives you the resources you need to succeed. Your success in his class depends on how much effort you are willing to put in. His lectures, however, are crystal clear and very straightforward, although sometimes he moves quickly. He's a great professor, and I learned so much from him

zach is the man!!! probably overhyped but he gives u everything u need to succeed if you do poorly its on you not him. His organic II exams are a bit too rushed other than that id say 10/10. Orgo is hard no matter who u get but Osner makes it possible to succeed if you try enough

I thought he was great! He's super approachable and kind. He video records his lectures, drops one exam and one quiz. An overall good orgo experience, considering the content is difficult by nature. If you study you'll do well!

I took him for CHEM 101 and he was the first chem professor whose chem class I scored well in. If you study well-taken notes from lecture and just listen to what he tells you to learn, you will do well in his class. He likes to refer to practice problems done on quizzes or in discussion, so learn from those!

I wish he taught every class at LUC. Hes THE BEST. Hes not easy but he has reasonable expectations and is always available to help. He makes orgo doable but you have to put in the effort. If you want a good orgo experience I highly recommend

Osner is perhaps the best orgo professor. He records all of his lectures, writes his notes out on the board at a digestable pace, and is always open to questions. He gives you all the materials you need to succeed and if you do not it is on you. Orgo is a class unlike any other science class before it but if you read the textbook you will be fine.

Osner teaches everything so clearly and gives you everything you need to succeed in his class. If you don't, it's on you. His exams are very straightforward but the subject material requires a lot of studying and practice to do well. Definitely utilize his office hours and ask questions, he's super helpful.

I absolutely loved taking Dr. Osner for Orgo1. The material isn't easy, but just so you keep up with it and do lots of practice problems it is possible to get an A! He hand writes his notes on the board which makes it easier to keep up with, assigns wiley hw for points, and all quizzes are group quizzes. One of my favorite professors so far!

After the 2nd exam everything gets really hard- final included. Owner is nice but not extremely accessible. A very smart guy, expects you to keep up and understand. WileyPLUS for homework but is good material to study as he picks out the questions for the class. tests are hardwritten by him- sometimes he makes mistakes.

Osner is a great professor. The material is difficult but knows a lot about the subject and is VERY good at explaining things. His lectures are organized which helps a lot for Orgo. He expects you to know the material well but he also prepares you well if you keep up with the work and study the material. Super nice guy and a great professor!

Very simples lectures. Definitely go to class as lecture material and examples are basically his questions on the test. He is very helpful and went above and beyond to help me not only with the material, but also my future in chemistry. Possibly the teacher I respect the most.

Very thorough lectures, emphasizes mechanisms and understanding rather than memorization; decent amount of the content 30% is not in Klein textbook so you really do need to attend lecture and take notes. Highly accessible at office hours and clearly answers questions. Tests are fair, you know what to expect, graded fair to arguably generous.

Osner is good at teaching the material and making it understandable. O-chem is hard no matter what, but he makes it bearable. Exams are tough but curves them if the average is low and also lets you do corrections for some of the questions. Homework and quizzes are usually pretty easy. The final exam is hard but doable. He's also hilarious and cool.

Dr. Osner is a great professor for organic chemistry especially during online school. He uses a white board to explain the material and it's really straightforward. He emphasizes the importance of practicing, so there is a lot of wiley homework assigned but it really helps. To get an A in this class, you definitely need to put in a lot of work.

His lectures are synchronous, but you can choose to just watch them asynch. His lectures are very thorough and backed up with plenty of examples. His tests are definitely difficult, but there's a curve in the grading scale and exams are curved. I don't remember anything from 101 (bad prof) and that hasn't been an issue for me in his class.

I've taken Dr. Osner for all of my chem courses at Loyola but one (I took him for CHEM 101, 223, and 224), and he is a pretty amazing professor. His lectures are extremely organized, and he explains the material well. He's also very open to helping you outside of class and gives you many opportunities to practice the material. Straightforward exams

Dr. Osner was absolutely my favorite professor. You definitely need to study more, but its because chemistry is not easy. He lectures by writing on a board, no PowerPoints, and I loved that. I also did not read, and I ended up doing fine just on lecture material. He gives everything you possibly need to succeed in this class. Wiley assignments too

Professor Osner is amazing, I wish I took him/could take him for more classes. He really makes all the material you learn stick and cares about his students. He always welcomes questions, is interactive, and does not make exams crazy and unfamiliar. He makes organic chemistry interesting and makes it approachable.

Professor Osner was amazing. I thought he made this class super easy. He drops the lowest quiz and exam, he was super understanding through COVID, and he offered extra credit on homework this semester. Exams can be tough, but I didn't think they were bad. He curves the exams if the average is low. Best orgo professor hands down, so take him.

Cannot possibly recommend another Ochem professor. I had someone else for ochem 1 last semester and did not enjoy it. I came to Osner's class and it was like night and day. Makes things super easy to understand. You really have to work to understand the material because the exams are long and sometimes tough. Lectures are fantastic.

Makes it reall easy to understand content in this class and is always ready to help.

For chem101, I think hes one of the better professors. The stuff itself might be a bit confusing, but he explains it pretty well and will answer questions. Theres a lot of homework on alecks, pretty much 3 days a week and then group quizzes and three exams where one gets dropped. Hes clear on whats on the test and will review in discussions.

Definitely a solid professor for gen. chem. You can breeze through his MC portion of his exams IF YOU STUDY. Short-response portions of his exams challenge you to think critically. Drops the lowest exam and quiz. Approachable and cares about student performance. Always willing to post helpful resources to prepare for the exam. Def one of the best.

Solid choice and pretty good at teaching, though I'd suggest sitting closeish to the front. Lectures went a little slow for me, but I already had AP Chem. Even if you struggle in chem you should be able to pass this one. I suggest reading the textbook, it really helped cement the lectures for me.

Dr Osner is probably one of my fav professors. Hes great at what he teaches. I knew nothing about chem and I learned a lot through him. Hes super funny and nice. He always made sure all the questions were answered. He connected with all of his students. 100% would take again. I highly recommend him. Its definitely a tough course though

Dr. Osner is a great professor and does a great job of getting the content across to his students. This semester he used a new grading system that many students, including myself, were not accustomed to which hurt many at the beginning. The grading system is not too bad but it does take some time getting used to. Expect exams every 3 weeks.

Dr Osner tried a new grading system for Orgo 1 and my experience wasn't as bad as others. He was clearly overwhelmed and disorganized, but I think he tried hard to help students and be flexible. No matter the grading system, he is a great lecturer and has intense exams. If you go to office hours he is very personable.

Dr. Osner makes his lectures very interesting by adding stories that make the class atmosphere light and non-boring. For CHEM-101 he went into great detail about every subject in order to give us a greater understanding. He seems like a very nice guy, and he somehow makes chem a little more enjoyable.

Dr. Osner is the best Chemistry professor. Take him if you can.

The best chem prof in the department. Great lecturer, explains concepts very well and is super open to helping students. Welcomes all questions and doesn't mind going over topics The only thing I would mention is that he doesn't respond to emails, so if you want to talk to him you'll have to catch him after class or during OH.

He is a good professor, funny, and has good lectures. He lets you use your notes for the quizzes and is willing to help whenever. He doesn't answer emails all the time. His exams are a tad tough but he gives you materials and formulas so you don't have to memorize everything. Aleks sucks and is time-consuming, but it helps with the material.

Even after switching my major out of Bio, I still love talking with Osner. I recommend him to all my friends who need orgo because he makes the class so enjoyable. I loved orgo because of him and he was a great help. You will absolutely succeed with him. He's great to talk to about non-chem too. His cat is adorable as well! If you can, TAKE HIM!!

Dr.Osner is amazing, I came into this class after hating the thought of Orgo due to a bad experience with another professor, but Dr.Osner not only teaches Orgo but he makes it some what enjoyable. Take him without any doubt, his exam questions are tough though but I would definitely take any class taught by Dr.Osner.

Dr. Osner makes things very easy to understand and his lectures are always entertaining and captivating. I'm not a huge fan of chemistry, but if I have to take it I will continue with Dr. Osner. He sometimes has a blunt personality, but if you get to know him you will like him.

Dr. Osner is a good professor but the class was difficult. The tests were difficult and sometimes contained things that we didn't discuss a lot in class. There was A LOT of homework. I would recommend to take him if you don't mind a challenge. He also doesn't really respond to emails that often so it can be hard to reach him outside of class.

He is a very good professor and very good at explaining things, but his exams are a pain.

Osner is goated. this is the first time I ever understood chemistry and enjoyed learning it. tests are extremely easy if you study but I had to study A LOT to feel that way. seems super intimidating but if you talk to him in office hours he is so nice. attendance is not mandatory but go to class. TAKE HIM he's an amazing teacher!

Professor Osner is an amazing professor, however his tests can be very difficult so start studying early. His lectures are him writing on the board but I feel like I learn better this way than reading straight from a powerpoint lecture. Discussions were fairly easy and a good way to keep your grade up.

Professor Osner is a really great chem teacher. I've never really understood chem, but his lectures were very thorough and clear. I got a 40% on the first exam, but 100% on the second. He records and posts his lectures, as well as all the discussion WS. He also posts exam study guides. Overall a really nice person and a caring teacher.

(Fall 22) Best chem teacher I have ever had. Legitimately knew the content and knew how to teach it. I wish he had taught Chem 102 this semester, I would've done anything to have had him again.

I think he is the best orgo 2 professor. Tests are fair and not tricky, but you still gotta put in the effort. He drops the lowest exam and discussion. He writes everything on the board. Records all his lectures live. Provides practice sheets before exams. I hate chemistry, but this class was somehow bearable with his (somewhat) comedic persona.

Orgo 2 is very difficult no matter who you have but Osner does a great job of explaining the material and tries to makes it easier to understand. His exams are definitely tricky (he drops 1) but does a good job at preparing for the final. Really funny, laid back guy that knows what he's talking about. Highly recommend taking him whenever you can.

He explains things really well and the homework assignments were super helpful for studying. The only problem was that the exams were definitely super tough. Like I'm talking I was tearing up on a short answer question once because it was just so wack. He's cool though.

Orgo is hard, but Dr. Osner makes it less scary. He is an amazing lecturer and does so many practice problems that nothing on the exam should come as a surprise. Of all of the options you have for orgo profs Osner is definitely one of the best you can have. He is also super cool and funny.

Dr. Osner is a great lecturer, and his exams are fair. I felt like this was the one professor who wasn't trying to deceive me and prepared me well for the exam questions. He is very accessible for help during his office hours and prepares you great for the final exam!

I LOVE DR OSNER! He is such a patient professor that understands how hard organic chemistry is. Many professors get annoyed with "dumb" questions because this is their life, but he understands that it takes a long time to learn the material. I would definitely take him again! Super super nice guy.

If you can take Dr Osner do it, he knows what he's doing but definitely is a better orgo teacher than gen chem. He loves when you go to office hours and it WILL help. Practice and pay attention, the book didn't help much.

I love this man. I have never been good at chem and was espically scared going into orgo but Osner is a god send. He never tries to trick you on exams and I never left his class feeling confused after lectures. He also records his lectures which are a huge plus. he is super straightforward on what he expects and will prepare you for the final.

I love Dr. Osner so much- he made orgo so easily digestible and his class is very easy to follow. records all his lectures, very accessible by email/office hours, very fair homework (completion graded), and super fair exams. His discussion questions prepare for every exam and the common final was very straightforward. silly dude- fav prof so far.

Literally the best science professor at this school. Hes so helpful at office hours and is always willing to help you understand questions that you may find stupid. I gasped with joy when I saw he was teaching this bc I had him for 101 too. ORGO is literally a foreign language but he makes it so manageable if you put in the effort to learn it.

Dr. Osner is a great professor who makes difficult material much easier to understand in lecture. Speaking of lecture, GO TO LECTURE. The book is fine but you will struggle with the material without his guidance. Even though Loyola decided to put orgo into freshman chem, Dr. Osner makes it manageable. A little hard to contact out of class.

Buckle up because this class is 100 times harder than 160. I thought 160 was a joke class and found it easy, but oh my god I was not prepared. This class is the hardest class I have ever taken and I've taken AP chemistry b4 and done good on the exam. Osner prepares you well for the test but you MUST/HAVE to take advantage of office hours/SI - GL!

I think Osner is a great teacher for an incredibly difficult class, he clearly knows what he is talking about however there was definitely some inconsistencies here and there. I feel like a lot of the problems were less his fault and more the system's, the class is super hard but if you got to OHs and study you should be okay

I loved having Dr. Osner this semester. I took 160 last semester and I received a C+. I barely survived that class, but with my new mindset and having Osner as an amazing professor I was able to get an A in 180. It really is doable to do well with the new chemistry system, but be ready to PUT IN THE WORK. Osner definitely helped make it manageable.

honestly, if you thought 160 is hard or you had to retake 160...you're not making it past this class. If you're pre-med and thought 160 is hard...just save ur trouble now and drop. This class is ridicously hard and if you're not naturally good at chem you're done for. U will struggle a lot and cry...Osner a G tho. praying wont save you nor studying

The level of difficulty compared from 160 is INSANE. Newman projections and those stuff is such a JOKE compared to what you will be doing. If this is ur first time taking 180 especially if you struggled with 160, youll be retaking this class again lol have fun.

for those taking 180 with him over the summer....uh good luck? you'll pass out. And if you do make it thru, you will def not be prepared for chem 240 lol especially if u took 180 over the summer.

GO TO OFFICE HOURS!!! This class was a nightmare content wise and a lot harder than 160. That said, Osner is really good at explaining content when you have specific questions (he might stare you down first) but it'll help. If you can take him, take him.

During the summer he is fine, but during the school year he comes off being pretentious. He records stuff and posts lectures but youll find that he makes a decent amount of "innocent" mistakes in his lectures. Def one of the better options but tends to cover a lot of material and a lot of mechanism which can leave you confused. Tests are tricky

Chem180 with Osner is no joke - the content is crazy hard compared to 160. But going to office hours helps a ton, and using resources like unstuck AI for extra practice made all the difference. It's a tough class, but doable if you put in the work.

The chem program at Loyola is already hard enough and stupid. Dr. Osner actually teaches chemistry, is very available outside of class, genuinely enjoys teaching. He is very easy to talk to if you are struggling and need genuine advice or help. He's also funny. Definitely take Osner if you have also never taken chemistry before/hate it/don't get it

Prof.Osner is a great lecturer. My only issue with the course is that it was graded ONLY based on your lowest category in the grade book. In his defense, this is not his policy, nor does the chem department (Devrey) let him calculate or enter grades for his own course, which I find to be a little insane.

Osner is goated. He is so good at explaining things. CHEM160 is hard, but he is accessible outside class, and can be asked questions 24/7 by emails. Go to office hours, he's for sure the best chem professor there is.

Chem 160 is going to be hard no matter who you take. I highly, highly suggest Osner because he genuinely does not want people to fail. He has a ton of office hours and will never be annoyed to work with you one on one. Also, while the class is pretty lecture heavy, he manages to make them pretty interesting. Really cool guy, take him if you can.

Osner is a wonderful professor who got stuck with an awful system. The new grading system is a total joke but he makes the best of it. He has a few OH sessions during the week and is always willing to help. He's also a cool and funny dude.

GOAT OSNER, but the chem department here is trash. If you work hard and actually do homework and practice problems, you can get an A. Don't skip class!!!!!

Chem at Loyola is AWFUL but Osner makes it a little bit better. He truly wants his students to understand the material and makes an effort to get to know you if you ask questions and go to office hours. He's the best chem prof I've heard of and always is there to help you (and is funny). Take him for chem!! And good luck on FOs and COs

Was really helpful and made his lectures interesting. Highly recommend going to office hours since the chem system is very difficult and can easily mess you up.

The chem department is bad, but he does a good job of helping you get the FOs and COs. There were times when he wasn't exactly knowledgeable about the COs/FOs, but that is because he doesn't make them. Overall, I would recommend taking him and definitely going to SI sessions or his office hours. Kind of a strange dude but overall a good professor.

I'm taking chem 180 right now, and I feel like I've learned a lot from Dr. Osner's 160 chem class. I learned from mistakes I've made, and improved. I also really love his lectures! He records them, and you can watch them again. When doing hw, we used ALEKS if you're wondering about that. I enjoyed taking him!

Osner is the 2nd best chem professor behind billingoat. He is by far the best for 180, and is a pleasure to be around in office hours. The wiley plus is quite annoying, so I often just focus on completing it rather than trying to absorb the material from there. He teaches how to do each FO and CO in class, go to office hours for extra explanations.

I really enjoyed this class and would take him again. I felt prepared and ready for what the COs and FOs were supposed to look like. I would have gotten an A- but I got lazy and did not work as hard for the last exam. That is my fault not his. I really liked how we learned through practice problems and work in class rather than just slideshows.

Osner makes the chem system at Loyola not seem so bad. He clearly goes over the different FO and COs, something that not all professors do. His lectures are great. I would totally recommend him and I think he is one of the best options. He does have a way of making you feel stupid when you ask a question though... he just seems kinda judgmental.

Osner is my king. The chem system sucks but his lectures were great and made it much easier to pass the tests. He lectures at a great pace and is very clear on the topics and explains them well. He's also super funny and cool. I'd take him again for 180 if he was teaching it next semester.

Dr. Osner teaches both types of topics (Both FO/COs) with a lot of clarity and constantly reminds you of upcoming deadlines and exam dates. He does allow his students access to previous lecture recordings, which were helpful for review. The grading system is un poco loco but focus on practicing the topics and you will get used it! Good luck.

the whole chem system is annoying, but bro's a good option to ease u into it. CO/FOs taught really well. Has time for reviews. Some teachers r more willing to give u dat pt and how he grades will ragebait u. But he was great, love him, def take him. Just go to class and don't be a bum

Chem 160 has been frustrating for many students primarily for 1 reason: students not only have to learn chemistry and its complexities, but also the mastery system at LUC. Dr Osner provides great feedback as to why something isn't considered mastered and engaging the students to participate. Very cool professor.
