Worst nightmare.I know 6 students failed and few got "D" You don't learn anything, have to study on U'r own.He doesn't give credit for U'r hard work, but he's so laid back. Unless if you are Korean student who study so hard or a very smart student, do not take his class.
No Comments
Useless class. You have to study on your own very hard. No extra credit, nothing. You can get a better professor for your money. If U take it you'll be sorry.
poor teaching style. tests are tricky. i swear. it took about a week to respond my email. he's not very helpful at all.
i think he is very kind and helpful teacher. whenever students ask questions, he explans very well and he gives many extra credits. and his class is never difficult if you study a little bit in the class.
O'Brien is a good teacher, but chemistry is difficult and very dull at times. He tries his best to help us understand the material and the tests are straight forward. He gives plenty of extra credit too. I like how organized he is. Let's face it...he is better than most of the science faculty at Nova.
he is very helpful and kind professor. he gives a lot of extra credits. but it is just like a pop quiz.also, his exams are same as the pratice exam. if you study a little bit hard, you can get A from this class. he is a very good professor.
Repeats material a lot. Doesn't seem to have a passion for the subject anymore. Pay attention and you'll do ok.
I don't know where these people are getting the idea that he is difficult, if you go to class and listen just a little bit, you will pass.
I had a 4.0 before this class and I graduate in the spring. Goes off on tangents, no study guides, you have to memorize the entire chapter, and remember minute details that he mentions off hand in class.
He is very helpful and good teacher. I was VERY bad in CHM when I was in highschool. BUT I still got A. All you need to do is listen what he says and go over the study guide. You should be able to do well.
Worse teacher everrrrrrr , please don't ever take him:(
I liked this professor. He is the type of professor who really knows his stuff and he's willing to teach you as long as you show your interest and give him your time. He's not mean at all, but he's also not going to hold your hand and walk you through everything. He's clear repeats the necessary stuff so that you don't feel lost.I highly recommend!
He is not only a great Chemistry teacher, but probably the best professor I've have had up to date. He is clear, straight forward, grades fairly, and just expects you to do the work plain and simply. He is nice and has a sense of humor, and he makes the subject easy to learn.
Great professor, highly recommended. Lots of opportunities for extra credit, easy exams, easy to understand.
he a really great teacher. i definitely reccommend him
Best teacher I've ever had; and probably the best chemistry teacher out there. Clear, straight forward, and teaches in a way that's understandable.
He's a great teacher and is very funny. Most of the students love him. Tests aren't that hard, but if you are not good at calculation you may find it quite difficult. I would recommend you to study the study guild on the book and you'll do well. I received 90% average on all of my tests.
An excellent Professor!! I took him for Chem. 101 and 102. Teaches both classes similar. Gives out "pop" quizzes(but tells you when they are) and they only help you. it's extra credit on tests. The tests well like any other you need study!Chem is not an easy subject but he truly makes it understandable. labs help grade (no quizzes or tests on labs)
Professor O'brien, to put it crudely, is the shiz. His class was awesome and he made chemistry awesome. I took chem 111 and 112 with him and it made me completely interested in chemistry. I'm taking organic now, and I credit my grades to him. Grades fairly, answers questions, has a sense of humor, and makes the class interesting. :)
Prof. OBrien is the best.He's not as easy to get an A grade as my CHM 101 teacher, but I learned so much more from him.He's funny,interesting, and very fair.
He is very helpful and knowledgeable. He relates the CHM concept to our life, so I have learned a lot from him. His lab class is so easy and no stress at all! So many extra points from easy quiz question every 2 weeks. He's very warm and sweet. If you read through textbook, Easy A! I highly recommend him.
If you loathe the thought of taking Chemistry but must do so for a pre-requisite, take Professor Obrien. Professor Obrien provides you with a system and spoon-feeds you anything that is even remotely challenging. Literally, this guy will do everything but hold your hand to make sure you understand the material.
A lot of information to learn if you've never taken chm before. Not very helpful in providing assistance if you don't understand the material.
He's a horrible professor I'm getting a good grade but for chemistry 101 he makes it so hard, I study 5 hours a day just for this class. He doesn't explain the material good at all, everyone is struggling with him; nobody understand him at all. All I can tell you stay away take and take it with somebody else.
Don't take him unless you want to fail his class. he's so helpless . Exams are so hard. No syllabus,everything is so unorganized. He will email you the night before the class around 9 or 10:00 PM to let you that there will be a quiz in the morning. so hard and trust me he doesn't want his student to pass the class.
Studying for the exam 3, so much to cover. its so hard to remember all these formulas and we have no idea what is going to be on the exam. No study guide or help from him. OMG so overwhelmed with this professor. he expect you to memorize every single word in each page. Stay away from him. Horrible teacher.
If you don't have a background on Chemistry, you're screwed don't take take him. He's helpless and he doesn't care about students. If you don't know the material, he thinks that you're stupid, instead of helping you to achieve and pass the class.
I took his class biased on the pervious good comments, but it came out completely different. Nothing is organized, u don't know when is ur quizzes or the exams would be. He's all over the place. He's exams r hard, mostly workout problems, not many multiple choice. He's a nice man but not good at teaching.
Very good teacher. Patient, understanding and works well. Gave extra credit often and explained the material if you didn't understand. made material practical and relevant to everyday life. Would definately recommend taking this professor
Very easy class. Professor gives a very clear explanation of all the stuff that will be on the exam. Labs are very easy and much extra credit for the class. The class is very easy and he is very lenient. Will accept work very late without taking off points. Very easy class
Not an easy class,hard grader. Horrible at teaching. But nice guys.
He makes you feel pathetic. It's a really hard class for chemistry 101. Not an easy class very hard. He's not made for teaching. HARD HARD CLASS. Impossible to pass with this guy. Stay away, he will bring your GPA down.
If you want to enjoy your time in college and have the option of not taking this class with him. do yourself a favor and keep away. Terrible grading system. He's is a very nice person but his exams are bone breaking heart crunching. He won't help you.
You will be better off to study on your own. Horrible professor, he's not helpful at all. He's test are skewed and designed to trick student. Is class is opposite of learning and it's torture. You will bring your GPA down by taking him
Extremely hard to follow. I don't recommend taking his course. Nice guy, However very hard to understand, unorganized and unclear. Hard exams. Worst teaching style! Avoid him by any means... He goes too quickly over the material without clear explanation so you will be lost in the lecture and fail his tests!
Worst Professor I have ever had in my entire life. Not helpful whatsoever and very demeaning and condescending. I am an A student and I had to work very hard to get a C in the class. DO NOT TAKE THIS TEACHER!!!!! The adviser told me not to take this class but I wanted to get it out of the way because I usually enjoy taking a science class.
just one word, STAY AWAY, he has definitely some kind of problem. he makes chemistry 1000 times harder of what it is. he doesnt like to help you but just to show you he is knowledgeable and you are not. chemistry 101 is very easy there is no reason to make it hard for student. i dropped with him and i took with another professor and i got 97.
he WORST professor NOVA has! He makes u memorize unnecessary material for exams!ie chem equation, I would say the whole book!. u won't learn chem- u'll just regurgitate his lecture notes and forget it the sec u step outside the classroom. BAD BAD BAD!!! STAY AWAY
I am good with chemistry, and this is the worst class I ever took. Dont believe in what he said, she doesn't know what she is going to give you in the exam. you better find someone else
Hard exams. he wont' help you to succeed. Stay away from him.
You never know what's going to be in the exam very hard exam. I'm a A+ student I ruined my GPA by taking him. Can't believe I'm failing this class, I have A in my other science classes. Profs can make a huge difference in your carrier! I hate chemistry cuz of him. I don't want to be chemistry major anymore! Horrible
No sense of humor, he won't give you motivation he will put you down. No study guide, he expects you to know everything in the book, so true. Honestly if you want to get a good grade take it somewhere else.
This class is extremely hard unless you know A LOT about Chemistry, higher lever, before. Im a chemistry major & Im failing the class cuz he decides to make the test to difficult. Some small percentage of people pass but more than half the class fails the tests. I study like crazy weeks in advance & still fail. Take someone else if possible.
Does not teach. Terrible teacher! He doesn't care about the students well being. Very disorganized. DO NOT TAKE HIS CLASS!!!!
He does not prepare you for his tests at all. Terrible at teaching. Makes it way harder than it needs to be.
you better off to teach your self. He doesn't care about the students. Honestly stay away. Horrible teacher that I ever met. I had drop 2 of my other classes to just focus on this class. his tests are nothing like the practice test. No study guide and so unorganized.
two words, STAY AWAY. horrible at teaching. Nice guy but careless about students.
Whoever has given the last 20 negative reviews should have spent more time studying chemistry than venting here. Professor OBrien is actually a great teacher!
I had to drop his class.
I passed his class with a C. He's a horrible teacher. I truly believe that he shouldn't be a professor. He's not good at teaching. STAY AWAY
He is a man that think very highly of himself for no reason... If he doesn't want to help you he won't... And all that. He cares nothing about his students and has an out of this world ego, he thinks hes above everyone. Do NOT take him!! Report this rating
He is the most annoying insensitive professor. He tries his best to ensure that no one cheats. But while doing this he makes you very nervous because he is all over you shoulder.
Don't take this teacher, he is the worst. Doesn't care about teaching, doesn't care about you. Annoyed if you ask questions,huge ego. More than half class failed.
I didn't pass his class, I'm a A student. Worked so hard to pass and get a good grade. He's not made for teaching! He just reads over the slides and writes a problem down with out explaining how to resolve the problem. Even though I fail his class, but IM SO HAPPY THAT I DO'NT have to see him any more. He's not a good person. STAY AWAY
I tok Mr. OBrien for chm 101 and 102 and got an A and a B.He did a good job. If you go to class and study a little it's and easy class.
I went to his class the first week. Not good at explaining materiel. Didn't like him. He seems rude.
OBrien is a good teacher, much better than others...less strict. Easy class. No attendance necessary, but you could miss bonus quizzes/extra credits towards exams. 5 exams, fairly easy if you study. Recommended.
Good prof. Fair to the students.
I failed chem in high school so so I SUCK at it. This class is hard, the material can be tricky. BUT Obrien is cool, despite all the horrible comments. five tests and drops 1, 75% of your grade. 25% is labs which are easy TRUST ME. there're extra credit quizzes. Overall, reasonable class with no final. Its hard, but manageable with studying.
Prof. obrien did a great job of teaching a bunch of characters in our class. He was fair and funny and we learned some chem.
I'm not really a chem fan, but it was fun learning it. labs were fun and educational. Prof. OBrien was very flexible and responsive to the student.
He is very nice gentleman who wants you to understand chemistry and get a good grade. Gives a lot of quiz to improve your grade. He goes over the material fast but always tell you what will be on test. Highly recommended!
The Prof was wonderful and extremely animated in class. He knew the subject matter well and was a very effective teacher.
I took this class and I had to drop it. Did not like how he acted towards me when I gave him my disability papers. Told him i was struggling and didnt even bother to offer his help even thou I tried to reach out. Chem is not my fortay but he could of tried a little harder as well. He is scattered brained during his lectures. I do not recommend.
Excellent prof.,goes over all the material you need to know. Always willing to answer questions. He enjoys chem and keeps it interesting in class. Go to class and you will do well.
One of the best classes I've had at NVCC
By far one of the most helpful professors I have ever had. He explained the material extremely well and all of his quizzes are immediately after he lectures on that exact material and they were extra credit points that are added to test grades, not a separate quiz grade. I honestly have so many good things to say, I would recommend him to anyone.
I would totally have a beer with this dude.
Professor Orien is very nice and wants all his students to pass. He gives you specific questions from the book to go over, and then modifies them for the test. Reading the book is paramount to doing well!
Seemed kind of bored by the subject material, finished every single lecture with "This isn't hard, people..." Nice guy, though, and helpful if you ask him. Labs were really boring, but not difficult.
Professor O'Brian is a good teacher and will make you laugh but, his leactures can be a bit confusing. Some of us just read the book or used the tutoring center to help us. He will help you if things are not clear and if you ask him. There are times when you might get bored in his lectures but, his labs are not that bad.
One of the BEST professors I've ever had! Laid back, really nice guy, loves to tell funny little stories. If you don't understand something, ASK HIM! He will explain it to you until you get it. Most of the test questions are the same questions from the end of the chapters, so do those for practice! GREAT GUY!! Highly recommend!
He is a good teacher. If you are good in Chemistry he is definitely the one to take. He is a little confusing in his lectures because he does like a little mumbling thing and his handwriting is horrific but I personally liked him. He made the subject easy for me and if I hadn't missed a month of class I probably would have gotten an A instead of B
I would recommend Prof Obrien for chem. He keeps you engaged and the subject fun throughout his lectures. There is no one that can teach chem as well and be so flexible as prof Obrien. And chm 102 is an easy A.
I would take Professor Obrien again in a heartbeat. He covers everything in his lectures, but you definitely need to read the book (easy read) and do the practice problems /practice exams. Do your part, because he always does his part. The textbook helped A LOT so make sure to get it. Loved his class b/c you can tell he wanted us to do well.
Very easy going guy, always ends up telling some funny story without even realizing it, it was pretty funny. Exam questions come from the book so if you read and do the questions to practice ahead of time then you'll get an A for sure. He can be a bit confusing but it's only because he explains quick. Answers questions, so ask. gives bonus pts.
Best Prof at NVCC. Funny, easy going, and flexible, but makes you learn the chem if you want a good grade. Makes class and lab fun. Gives everyone a chance, but will give a bad grade if you don't study. Go to class because he explains everything well. Ask questions.
Nope nope don't take him he has changed everything that everyone said he's horrible . Everything he will tell you to study isn't really on the test . Those so called pop quizzes don't really bump up your grade he lied about that . He doesn't drop any test . Just don't take him
You have five test nine of them get dropped . He gives your problems out of the book he will say oh yeah there on the test. NO there not . Therefore the test are hard . You have to attend lab. The pop quizzes aren't any extra points so it will be a waste to even take them
Pop quizzes aren't graded to be added to your grade to bump it up he told a very big fib on that. Yes there's five test none get dropped . Testare hard don't really make sense . No need to set your self up for failure
I just finished a class with Prof. OBrien and he was great. I have no idea what the previous person is talking about ( obviously the same clown wrote the 3 last reviews). Class was fun and we learned a lot of interesting stuff. Prof. OBrien's tests are fair and right from the book, and he does give "pop" quizzes that add points to your test score
He is super considerate and thought. He will reinforce the need to study, or practice. When class ends early he gives us the option to stay back and have group study or get his help. If you attend class and practice with the homework you should get an A. It not super easy but we should all do our part. He certainly do. Took class January/18
Great professor with a good sense of humor. Assigns homework for your benefit but doesn't collect it. Exams are fair, labs are fun. Gives "surprise pop quizzes" for extra credit often. Not too heavy on power point, uses it when needed. Read your textbook, do the practice questions, and you'll do fine. Would take him for any chemistry course.
Nice guy. Lectures can be monotonous but if you pay attention, he really is explaining well. Tests are harder than the practice tests, so beware. Study, do the practice problems in the book and youll do well. Labs are fun, tests are hard. Im an A student & got a B in, but Chem isnt my thing. No complaints. He does his part. Do yours.
Horrible teacher and person. Extremely frustrating to work with. His lectures make little to no sense and his explanations are pointless. I showed up to 4 classes this semester, failed two tests, did all of the homework assigned (not graded), and still passed with a B because lab saved my ass. I would never take him again.
Chem isn't my strong suit and he's not really a good lecturer, pretty much have to teach yourself. test are based off the recommended questions but theres a lot. does give bonus quizzes to help your lecture grade. lab is easy.
He was the rudest teacher ive ever seen in my life, this is the first bad review ive ever written on this website. avoid his class
Prof. Obrien is a good teacher. He makes it easy to understand. You do have to study but he does his part. Class and lab are fun.
Would take the class again, he is the only one I can see teaching this at this campus. He is accessible during his office hours and gives extra credit points My advice is to do the homework, it's not required but he may use a few HW questions on the test/quiz. Get into his office hours or additional tutoring if needed.
Just finished chem class with Prof Obrien. Class was easy and fun and we learned some chemistry. He goes over all the stuff you need for the test.
I would not recommend taking this professor, i honestly didnt learn anything and had to teach myself. His lectures are long and boring. Did enjoy lab though.
He is not the best but he knows his stuff. It was just hard material. He rambles on a bit but nothing major. Would recommend
He does not help you to get a good solid grade. Please do not take him because his test only average up 50 questions each 5 tests, you're given not enough time, if you came late to class. Must study every second of your life to boost your GPA. Beware of Pop-quizzes because they can your life ( bonus points). Get Help from the science tutors.
Great guy. Funny. Easy A.
Just took chem this summer. I think there were 10 A's in the class of 15. Mr. obrien was great and very entertaining. Highly recommend.
Class was fun, especially the lab. Easy A.
Professor Obrien is a great professor with a great sense of humor. He is very kind, easy going and flexible. He always made an effort to help students in need and made himself available. I really enjoyed learning from Professor Obrien. He made class and lab fun, engaging and enjoyable.
Mr. Obrien is really nice, but he's not direct when you ask questions. The only grades for this class were the labs & the tests. All the quizzes are bonus points that he adds to the tests later and you get an optional project to replace the lowest test grade. Just show up to class on time, do all the labs and use the study questions & you'll pass.
He doesn't explain very well. he's so caught up on the details that he misses The main point of what we're learning. It might be clear to him but, students we're learning the subject which Makes it harder when you have so many details to focus on. He's not understanding, Mainly thinks that chemistry is the only class ur taking in that semester
