Really enjoyed the class

Great teacher, very enthusiastic. Always willing to help and very clear in lectures. Only person I know that makes a 2.5 hour Chem lecture interesting.

great teacher.makes you understand, not memorize

Great teacher! really knows what he is talking about. Very helpful. Makes class fun.

Extremely helpful, but the course was very hard. He wants everyone to pass, but won't just hand you the grade. Lectures were clear despite the difficulty of the material. I can't imagine trying this course with any other professor.

Duff is best chem teacher I have taken.He's willing to help you learn and tries his best to explain the material.His tests are easy if you do the practice tests.He focus more on logic than memorization.You can't go wrong if you take him.(Good/funny guy)

very helpful teacher. stays late in labs if needed. really cares about students and is an all around nice guy

Great teacher. Although the material is hard he makes its second nature for you.

The class was really hard, but he is an incredible professor. He's easily the most enthusiastic professor I've ever had and he definitely knows his stuff! He was always more than willing to help anyone who was having problems. I would have lost my mind if I'd taken the class with anyone but him.

The class is hard because of the material, but it would have been much harder without him. He's excited about what he's teaching and keeps you interested.

Organic 2 is much easier than one, regardless of what he tells you. Labs are fairly easier aswell. This is considered a weedout class at most universities due to the material. Duff makes it easy, yet can be confusing at times. He's such a spaz so expect your tests to get graded late.

DUFFMAN IS IN THE HOUSE, OH YEAH!

He's awesome...funny guy too...i love going to his class and his lab is excellant! Great professor.

He's smart and knows everything about the subject, but he throws a lot at you. He's way cool, but he makes you learn stuff too. That's the best kind of teacher. VERY VERY HELPFUL, If I could, I would give him a 7 or 8 on a scale to 5.

TONS of material. Gives practice tests and real tests are basically the same. VERY unorganized and all over the place. REALLY knows his stuff. Will help you if you ask. Great sense of humor. Labs are pretty easy as long as you follow the guidelines. He can be a bit confusing because he swaps terms a lot and starts new stuff w/o explaining new terms

Good personality & sense of humor, cares about students. Organic is hard and he makes you learn it, but he goes out of his way to help you if you ask for it. Practice tests help alot when he has time to make them. HW is optional, but that not doing it can hurt when the exams roll around...

New book he is using is really good. He's a cool guy too!!

Hard Class. Good Teacher. He always reiterates his office hours--he's very willing to help you if you just put forth the effort. Oh, and there's a lot of effort you'll be putting forth. If you truly put for the effort, there's no reason why you shouldn't get an "A" Other than that, he's a good person with a great teaching style-you'll have fun

I think he's not a bad teacher just a bit hard. If you care even a little bit about chemistry then take him, you'll actually learn chemistry. If you just want an easy grade take another teacher. Also look over the book sometime before you take a test, it's helpful

tests are extremely hard but he's super helpful. make sure to go to class and to ask for help during office hours because he goes very fast.

I took him for CHEM 1 and I came back for more. The subject is hard, and--therefore--his class is hard. He might not be the easiest teacher simply because he wants to make sure you learn the material. ..If you want an "easy" A, don't take him and drop out of college (ur too lazy). ..If you want to LEARN, work hard, AND get an A, TAKE DUFF!

Kind of hard to follow, jumpy and erratic. but a very good teacher and helpful. Definitely would take him again.

Great teacher and makes Chemistry seem interesting. Practice exams are for kindergarteners compared to the actual tests. Don't expect to get an A.

Duff has got to be the most enthusiastic teacher I have ever taken. I came into his Chem 1 having hated the chem I took in high school, but I enjoyed the class so much that I continued and took chem 2 with him as an elective. He is NOT an easy A or even an easy B, but if you are struggling and you ask for help he will not leave you alone.

Very knowledgeable professor. VERY HARD CLASS! You must eat, sleep, and BREATH chemistry just to PASS! Notes are all scattered and don't help much. His practice exams are nothing like his tests. On the contrary, he is VERY helpful during and sometimes not during office hours. I went to him practically everyday and still got a C. Advice: WORK HARD

The most passionate professor I have ever had! He LOVES chemistry, loves teaching, loves helping his students to succeed. If every instructor were like Prof. Duff the world would be a great place! Work hard to earn your grade! His class is not easy buy he offers every opportunity for help and guidance, so take advantage of it!

Awesome and inspiring teacher. Knows exactly what he is talking about and can use examples so that everything makes sense.

woowww i love dufff i would change my major to chem right now if i could take him every time class is hard but just study ....out side help is good. built in bonus point on every test

Excellent professor. The subject matter is difficult, but Duff will take the time to answer any questions you may have in or outside of class. Really knows his stuff and is very enthusiastic. He is by far my favorite teacher yet, but you need to be prepared to put the time in. Tests are difficult and detailed, so no winging it!

Duff is the best chemistry professor at the school take him and have a chance at passing Chemistry if not you will fail this class. Duff is entertaining and has great knowledge of chemistry

Subject matter was hard, but is willing to help. Go to EVERY recitation to show him that you want to make an A.

Best chem teacher at the school. Very respected. I'm literally feeling bad for my B in the class because I was the one to completely blame for not making an A. He makes me wanna change my major to chemistry. Very inspiring and smart. Take him and have a chance at passing chem at SPSU.

Duff has got to be one of the best professors. My interest in organic chemistry blossomed after his class. Very helpful. Class is very hard, but doable. Half of my class failed every test, and the class. Definitely the weed out class.

Great professor. Go to lectures, they help. You get 2 points for going to recitation. 4 tests 1 final. if your final is higher than one of your test, it will replace it. Tests are decently hard, but doable. make sure u do well on first tests b/c it's the easiest. Made an A. Lab is easy, LEARN SIG FIGS.

Duff is a great professor, but make no mistake, this class will break you. Copious notes and reviewing will get the grade. I got an A.

Very passionate about Chemistry which keeps the lectures interesting, though concepts can be hard to wrap your head around. While the class average on tests was <70, I found them doable(got As). My advice show up to class, study from the worksheets he gives you & the practice exams, as most of the questions & concepts come straight from them.

I've had Duff for Chem 2 (summer class and got a B), Organic 1 & 2 (got an A in both). Hard to follow, I got used to it and I NEVER opened the book. His test are hard, he will replace the lowest test with your final. His final will be the hardest test he gives. He really cares about his students. I wish I could take Duff for every Chemistry class.

Organic I. This dude is the bee's knees. He's very enthusiastic and is always eager to help his students. Subject matter is tough, tests are tougher than practice, and expect TONS of handouts instead of using the text.

Dr. Duff is an amazing teacher. Yes, he does go a little fast sometimes, and yes, he sometimes goes on tangents, but he loves what he does and you can feel it through his teaching. He is very open to people coming to him and asking for his help during office hours. He is also super fun if you have him for lab.

Best professor yet! He is a biker dude with a leather fanny pack who really knows how to lecture. Be prepared to take 9am class. Review the test reviews. I have yet to use the book w 109 on both the first 2 tests (I took AP chem in high school). Slackers may struggle, but attendees with prior knowledge WILL have an A.

If you never took high school chemistry, his class might be hard.

Professor Duff was easily the best professor I had this semester. He really knows his chemistry and he really wants you to be interested in it and to learn it. He is more than willing to help you understand. Take advantage of his office hours. He also has a great sense of humor. Would definitely take again.

Want an A? Go to class, read the book, DO practice problems in the book, and most importantly, GO TO HIS OFFICE HOURS. What was that? OFFICE HOURS. He won't turn you away, he will help you until you UNDERSTAND it. He's amazing, energetic, and loves Chemistry. He wants you to LEARN. THINK. APPLY. Hard class, sure, but worth it! It was a fun ride!

I took Duff for Gen Chem 1, Orgo 1, and Orgo 2. His lectures were interesting. His tests were tough, especially Orgo 1. If you pay attention in the class and come to his office hours, you will pass his class.

Animated, involved, excited, happy, just generally a great professor. A go to for any chem class.

Good lecturer. Goes through course material in-depth. Tests are pretty tough. Fair amount of homework, but he will help you through it during recitation. Keeps track of attendance with a sign-in sheet. Funny guy.

Great lecturer and easy to listen too. Does not use powerpoint really, so have to take notes from whiteboard. But explains material well and gives lots of relevant example. Attendance is mandatory. Take Duff if you can.

Dr. Duff makes organic chem lab fun. He gives pop quizzes, but if you do the required readings THOROUGHLY, you should get at least a B. Final exam was very straightforward. Class had a relaxed, lively atmosphere due to Dr. Duff's positive attitude. He willingly answers all questions and gives thorough pre-lab lectures. Highly recommend this course!

I have taken Duff for Organic 1 and Organic 2. Made A's in both. One of the most amazing teachers I have ever had. He is so helpful and hilarous. You have to work for your grade but overall the best teacher! GO TO OFFICE HOURS! And I have never opened my book.. Study his notes, practice and ask him questions and you'll do great!

Dr Duff is the bessssssst. The most helpful and understanding professor in KSU. If you study his notes and go to his office hours you will get an A. I just love Dr Duff.

AMAZING. Had Duff for Lab and honestly, a great professor! You have to earn your grade, but it's not hard if you put in the effort. Go to his office hours if you have trouble writing a lab or just need assistance with anything. Be ready for pop quizzes in lab!

Dr. Duff is a brilliant scientist and caring person. He wants his students to succeed and goes above and beyond what I have seen most instructors put forth in effort at KSU. His class does require a bit of effort, but I feel it better prepares you for the professional exams in the near future. Read the chapters and utilize the practice exams.

In lecture he's great. Organic chem is hard as it is, but he makes it bearable, and his tests are "tough but fair". In lab, he's so energetic and passionate about the experiment, but a bit of a harsh grader. Take him for lecture, but if you want an easier A in lab, take someone else.

AMAZING LAB PROFESSOR. If you don't understand something, go to his office hours and he'll explain it until you get it. For the pop quizzes, make sure you understand the labs inside and out! The labs are 50% of your grade so make sure to make decent grades on them! Look over the past quizzes and make sure you understand what you've missed.

I had Dr. Duff for lab and he was awesome. His final was ridiculously hard, but other than that, the labs were straightforward and he was a really lenient grader. Very clear guidelines and most of the time, we got out early.

Duff is hands down one of, if not the best, teacher I've ever had. Organic chemistry is hard but Duff goes above and beyond to help his students succeed. He is more willing to answer any questions both in class and in office hours. Pay attention in lecture, get him to help you if you need it, and you'll pass no problem.

Duff is by far the best college professor I've ever had! He made organic chemistry not only interesting but fun! He is very helpful in office hours and review sessions etc. He truly goes out of his way to help his students understand chemistry. 10/10 would recommend and take again! You have to put effort in to do well but you have plenty of help!

Print his notes and fill in as he goes. Work as many problems as possible and make sure you know how to approach the problems in the practice exams. His study sessions were great for me. Calling him lazy is the biggest mischaracterization - he's very passionate, goes way more in depth than necessary, but approachable when you have any confusion.

An absolutely wonderful professor, but SO tough! You can literally go over a test with him in his office for hours and he'll be happy the entire time. The only reason I would not take him again was because I did not like how fast-paced of a teacher he was. If you want someone who is "slower" and more in depth, take Alexander.

Had him for orgo 2. If you thought orgo 1 was hard, just wait! My advice, only take Duff for orgo 2 if you had him for orgo 1. It took me quite a while to get used to his teaching since I had someone else for orgo 1, and by that time, it was too late to pull my grade up, so I'll end up with a C. No quizzes at all. Just tests, homework, and a final.

He's a funny professor but sometimes he rushes stuff so it's harder to understand. I would highly recommend him for lab. As long as you do the reports and worksheets correctly you will get A or B. However does pop quizes before labs which can be hard sometimes and also he's messy with paperwork so he constantly changes schedules/assignments around.

one of the BEST professors EVER!!! the sheets provided and notes added are enough if you understand them and do the practice problems and practice tests! An Amazing professor i recommend for everyone and is always there during office hours for his students

Duff is a wonderful Organics professor. I had him for lab and he was a great help to my understanding of lab concepts. He is a tough grader but that is because he expects you to actual know what your are supposed to know. I would highly recommend him. His class is not hard, you just have to work a bit more but you leave having learned a lot more.

Professor Duff is an awesome professor! If you have the opportunity to take him for lab, DO IT! He is an incredibly caring guy so he will answer your questions no matter how dumb they are. he is enthusiastic about teaching orgo so his pre lab lectures are very engaging. Definitely take from Professor Duff

Very energetic. Not a tough grader, but he doesn't like to give 100. Has random quizzes, so come to class knowing the lab before and lab you're going to do that day. Don't be afraid to ask questions, Professor Duff wants to help. He grades lab notebooks throughout the semester, so keep them prepped. Makes quite a few changes to labs, so check email

I took him for gen chem 2, orgo 1 and am going to take him for organic chem 2. His practice exams are mostly the test. But you have to understand the concepts, memorizing the the practice exam is like 50% of the exam.

I wish Duff taught more classes, I would take him for everything! He is a super cool dude and great teacher. Puts all rubrics for lab reports online, grades fairly. Mini quiz over the lab protocol at the start of each class but if you just read its not hard. Final exam was cumulative but basically just all the quizzes put together. Very fair &amp; fun

I took this guy for General chemistry 1, Organic 1, and Organic 2. That is how great this guy is. His office is ALWAYS open, even if he's eating lunch. For the exams, just look at the old exams and you will be good. To study, this is the only book I have ever purchased since it was helpful. Please do not flake out on getting the textbook.

MY FAVORITE PROFESSOR AT KSU!!!! hes very passionate and always there to help!! I go to his office to chat daily and get help. HOWEVER I DO NOT RECOMMEND TAKING THE SUMMER SEMESTER VERSION WITH HIM. it is very hard and fast paced! 60% of people failed in ochem 2 ;(. take him during normal semester! He makes his own notes.

DUFF over TAPU anyday!! However, he writes his own notes which are very detailed so his style is kind of different. If you pay attention in class, he tells you what will be on test. his test are very hard but doable! He wants to test your knowledge. do not get behind and do not skip!!! easy and chill lab grader as well. took him for orgo 2 and lab

Prof Duff is a very enthusiastic and amazing teacher. He is always there to help and would also hold group help sessions if needed. Orgo 2 is hard and if you know you are not a fast paced learner do not take it in the summer. But for the spring and fall semesters, any class that you have to take and is taught by Duff, definitely take with him.

Great Ochem professor, his practice tests are basically his tests. He is all over the place and the syllabus is not set in stone, but he is an overall good professor. Easiest ochem class.

Teaches very fast and frustrates a lot of people because his notes are SO scattered, but if you follow along in the book, go to his office hours, and do the practice exams, you should be okay. A high rating on here DOES NOT mean he's easy! He's pretty difficult and MANY people failed. If you put in the work though and don't give up, you'll be okay.

Prof. Duff is AMAZING!! I thought organic chemistry was a difficult subject but it's straightforward. As long as you read chapters before you come to class, you will understand the material better and get a better grade. his exams are not that hard , it is either you know the material or not. the tests are very similar to his practice exams!!!!

Duff is a great professor, he is very scattered and not consistent but he is a great professor otherwise. Straightforward tests and HW, no online work, no mandatory textbook. Office hours are very crowded so you have to fight to talk to him. You don't learn much in class, but learning it on your own isn't hard. Never made below an A on a test.

Prof Duff is amazing. He made the class pretty easy for an upper level (&amp; notoriously hard) class. Go to class, pay attention, print out and write down what he says and you're golden. Do the practice exams, they're very very similar to his actual exams! And REWRITE YOUR NOTES!!! That helped me a TON. Awesome awesome professor!! RECOMMEND!!

Duff moves fast, is scattered, and can be unorganized but every professor has their flaws. His tests are similar to the practice tests and arent hard, but if youre use to getting an A without working hard that wont work in this class. You must put in work and make sure you understand the material beyond the practice tests or it will show.

He's a chill professor in lab with short pre-lab lectures. There are 3 lab reports and a couple worksheets. He has pop-up quizzes occasionally and a final. Pretty lenient with grading. Definitely recommend!

Duff is a little fast paced and always available for office hours. His tests are similar to his practice tests. Homework is extra credit. Curves some tests depending on the difficulty.

He is an easy grader in lab. He explains everything in his pre lab lectures but he will throw in a quiz every now and then. You can ask him questions without him making you feel dumb! If you show up and put effort, he will help you out!

I have taken Duff for Organic 1 and 2. He is incredibly caring, funny, and accessible whenever you need him. He posts practice exams and if you understand the concepts, you will get tan A-B. His written response are identical to the practice exams. He is a fast grader, you usually receive your grade the day after the exam. Not one bad thing to say.

Professor Duff is a rarity at Kennesaw. He makes you laugh every class and you can actually find that chemistry is interesting. You can easily get an A if you take his practice exams (of which he gives many) before his actual exams. He is always helpful during office hours and SI helps a lot as well. Best organic teacher at Kennesaw hands down!

Duff is one of the best organic chem professors at KSU. I have had him for orgo 1 and 2. He is always available for office hours and holds practice sessions before tests which are very helpful. He gives his old practice exams and they are very identical to his exams. He is a fast grader and lets the final replace one of the lowest test grades!

He is easy for lab as long as you write down all his per-lecture. He IS NOT a harsh grades. Always available for office hours. One of the best lab professor for organic hands down!

I do not have enough nice things to say about Duff. I never liked chemistry and I was never good at it until I took orgo with him. The tests are very similar to the practice tests so make sure you study those. They are very helpful anyway. Homework is optional, it will count towards your grade only if you want it to and if it will be beneficial.

Orgo II is no joke. It is a hard class, but Prof Duff is amazing. I had Tapu for Orgo I, and he is significantly better. He only teaches you what will be on the test, he is very engaging (not monotone), his tests are mostly multiple choice with some mechanisms and synthesis at the end. I would 100% recommend taking him.

Professor Duff is the best professor I have ever taken. Organic Chemistry is a hard topic, but he explains it so well. Do the homework, pls study the old practice tests because they mirror the exam, and take good notes in class. I promise you will be so glad that you took him. Also, he's very funny in class, so you will always be laughing.

Don't be scared to take Professor Duff because you did not have him for Orgo 1. I was in the same boat when I was going into Orgo 2. I am so glad that I took Duff. 10/10 choice. I had Haseltine for Orgo 1 and it was unbelievably hard; however, when I came to Orgo 2, Duff helped so much and made everything make so much sense. Awesome guy! pls take!

Orgo 2 is a very tough course, but Duff makes the content crystal clear. My advice: 1) Go to lecture and take notes 2) Go to SI sessions 3) Go to office hrs and ask him! 4) Study the old practice tests!!!(They mirror the exam) 5) Do homework. Only several due and they're easy. 5) Categorize the info when studying (it helps) Perks: He curves well!!

Professor Duff's lab is not hard. Just follow directions and turn in your work on time. Also, he does not make students write out the pre-lab lecture. Just print it off of D2L. Lab reports and worksheets are self explanatory. They can be difficult but just work hard and ask if you have questions. Quizzes occasionally, just study pre-lab.

Professor Duff is a great professor. He explains concepts well and very obviously cares for his students success. Put in the effort, get to know him, and ask him questions when confused and he will make sure you succeed in his class. The labs are not hard, but some of the questions can be tricky so start them early in the week.

Do not be afraid of Duff. Yes his teaching is different but he explains it so well! i took tapu for Orgo 1 and i'm taking Duff for Orgo 2 and honestly i feel so comfortable with the material after he explains it. He really wants everyone to pass so he will answer ANY questions during office hours or if you email him he will actually answer you.

Professor Duff is one of the best professor's for organic chemistry. I really wish I had him for organic one, but fortunately I still was able to have him. Duff is very determined and very invested in this course and I promise you he is always willing to help you out. If you can, take his lecture and lab at the same time, very helpful!

Duff is difficult to learn from, but wants to help students. He doesn't try to trick anyone on tests, and gives you practice tests that resemble the real thing. Read the text! It fills in the gaps you have from orgo 1 or what you missed in lecture. When you find your groove with Duff, you will love him! Passionate about chemistry &amp; very detailed

2 weeks until semester ends and still no grade for anything. Not clear about expectations for lab notebook or reports, so I have no idea where I stand in this class. He does care about his students, and is understanding of our struggles in this COVID semester, so I think he'll be generous. Wonky lab set up, but not his fault.

If I could take Duff for every class at Kennesaw, I would. I took him for orgo 1, orgo 2 and orgo 2 lab. His practice tests that he uploads really help. You have to put in work, but he makes it easier.

Prof. Duff overall is very chill. His pre lab lectures are super informative. As it is lab, you have to participate. This was more of a hybrid so we had half labs and half online worksheets. An important note: He was very slow at grading...I mean we took the final and still didn't have ONE lab grade back. Final was super hard btw but he did curve.

Take my man for lab. This was the first lab that I actually understood everything that was going on and why we were doing it. He explains everything perfectly in the prelab lecture. Checks lab notebooks on the first &amp; last day of class, so those are the only ones he expects you to do. He's always happy to help. I failed the final; still got an A.

He's a really chill guy . Lab notebooks take like 20min max because you don't have to write the entire procedure out. He walks you through the lab and is always happy to answer questions.

Duff is a great guy, and honestly made ochem a much better experience than I ever thought I would have. I hate chemistry, but ochem has been easier for me than chem1 or 2. I have a great SI who actually puts in a lot of time and effort to help us succeed even more in the class. Tests (with final included) are worth 90-100% of the grade. Recommended

Awesome professor. Approachable

Prof Duff is PHENOMENAL! He is so kind and explains material super well. He has plenty of time to go to his office hours. He is an easy grader and loves to teach.

His lectures are heavy on mechanisms, so if that's not your thing be prepared to study a lot outside of class, which you will need to do either way. The practice tests he posts, and SI was my lifeline when i took this class. I found the homework to make me more confused so i did this course without it. When i took his class homework was optional.

This is a hard course but Professor Duff makes it a little better. Duff is the best OCHEM professor at KSU! Very funny, personable, and interesting during lectures- so they're never boring. Lots of material, however. Study a lot! Take advantage of SI sessions and go to Duffs office hours and you'll pass!! You must put in the work and attend class!

He had office hours literally every day and would even extend them sometimes. He notices effort so if he sees you improve, he might grade a bit lighter. Great prelab and very helpful during the actual lab. He does like 3-4 pop quizzes and drops the lowest 2 but the quiz is just over prelab things and he doesn't make you write the procedure.

Absolutely the best professor i have ever had going into one of the most scariest courses in college. He was very nice to everyone and gave very helpful feedback in office hours.

Orgo is hard but if you put in the work you will do good. He is the best orgo chem prof at Kennesaw. He has office hours everyday and it shows he really wants his students to succeed in his class. Take him before anyone else for lecture!!!!!!

Duff is the best O Chem professor you can get at KSU! Takes pity on his class when he sees them struggling and bases exams off what he knows we can do. Does not use the ACS final and provides lots of practice exams that are almost identical to the actual exams. Hosts common study hours and doesn't make you feel dumb when you ask for help

Professor Duff's O-Chem class is tough, but he really wants us to succeed. His lectures move fast, so it helps to supplement with the textbook and tools like unstuck study. Overall, put in the work and you'll do great!

Such an amazing prof that will get to know you , obviously wants the best for his students. Most ppl that complain didn't come to class or office hours. Posts practice exams that are IDENTICAL to his exams

Best professor ever! Visit office hours and ask questions, you will do great.

My favorite teacher of all time. Very passionate about the art of chemistry. His lectures are extremely fast paced; don't miss a class! To pass, all you need to do is: Read the notes before lecture. Focus on the practice exams! (They're EXACTLY like the tests!!!!) Go to SI sessions and office hours. He WILL be there for you! Good luck!

Of all the organic professors, he gives the most clearest explanation to stuff. He also has a sense of humor and is easy to relate to if you get to know him. The class was difficulty but if you go to office hours and study regularly outside of class, you'll do great. He's also a people's person and doesn't act like a &#8220;PhD-Knkw it All&#8221;

Professor Duff is an excellent lecturer. He has teaching oChem down to a science! This is a very difficult class, but he posts lots of practice exams from previous years and the information doesn't change much so you really know what you need to know to do well
