Comment:
I'm not Raff, I don't even think the man looks at these reviews. But I am going to give Raff a 5 out of 5. Chemistry is a hard subject, that not everyone understands. If chemistry was easy, we would all be whatever we wanted to be without any challenge. If you want to learn from a brilliant man take this gentleman.

Comment:
He made CHEM1515 harder than it already is. His practice exams were nothing like the tests we received. Homework also was nothing like the exam questions. His lectures are uninformative and often leave you more confused than before the class.

Comment:
Amazing professor for both semesters of physical chemistry. Brilliant guy, but difficult. Very dedicated to teaching and will always help in any way he can. His tests aren't meant to be tricky, they just test if you *really* understand what he's been saying the whole time. He wants to see if you have gained a fundamental understanding of the class.

Dr. Raff is not a bad guy and he really knows what he's talking about. However, homework assignments are unnecessarily long and difficult. His exams were nothing like the practice exams he gave us. Lectures are long, boring, and not very helpful.

Comment:
Unnecessary workload when it comes to homework. It takes hours and hours to complete them, he treats it as if his class is the only one you're taking. He assigns 10-15 homework problems/chapter, however only takes 2 per assignment for a grade and you don't know which two, very frustrating. Tests are similar-ish to prev. ones which he hands out.

Comment:
Never had such a great professor during my time at OSU. He is one of the best junior professors for Chemical Engineering this semester. I learned a lot! Go to class and take good notes and do your homework. Go to office hours, he works out your homework questions if you ask him. 75-100 is an A. Not a difficult class.

Comment:
Taught PChem. Unbelievably knowledgeable. The subject is difficult, but he is a great professor, and you only need a 75 for an A. Homework workload is pretty heavy, but it does a great job of preparing you for tests. Listening in class and doing homework should be enough to pass tests and get an A.

He's a great prof, but the class is a difficult one, no matter who is lecturing. The grading is extremely fair. You will look back after taking this class and realize how great a professor he was, even if tough.

This teacher is seriously the worst you will ever have. He's not used to teaching undergrads, so prepare for a huge workload. Yes, I know we're in college, so we're are supposed to be challenged. However, this teacher takes it to the next level. It's almost like he wants you to fail. His average for his tests are all below 50. Be afraid!!!!!!!!!!!!

This professor was difficult but he was very clear about his grading and what was expected from you. Make and appt. and go see him in his office and he will help you greatly. It may not seem like it, but if you put in the effort he will help you.

Comment:
He's very friendly and willing to answer questions in class (it takes him like 5 minutes to understand what you're asking though). But, his homework takes hours (my tutors didn't know how to do half of it), the tests are extremely hard. The class has no curve and no bonus points. I would avoid taking him

This teacher was hard to understand and made the semester completely miserable. It seemed like he expected you to know higher level courses like physics to pass the class even though it is not a Pre-Req. Do not take this guy at all costs.

Dr. Raff is a dry, funny man who has a Hitler mustache, but the class is awful..I MEAN AWFUL!! Everything is different, the test, homework and material covered in class is all completely different and dont expect to do well on hmwk if you dont get help from a tutor or TA (which half of them cant explain it or dont have a clue)Dont waste your time.

Comment:
He is an extremely smart man, but teaches on a level far too advanced for this course. Lecture notes don't really even tell you what you should be learning. The book confuses you because it is not as complex as his lecture which caused confusion on whether it was the same material. You will NEED to get tutoring to survive his class.

Comment:
He does show much interest in helping students outside of class. He teaches physics and calculus instead of chemistry half the time. The only way to get any of his homework done is with tutors. Not even the TAs know what he doing on the homework. His tests are similar to a packet he gives before a test but it is hard to understand what he means.

Terrible teacher. Really smart but doesn't want to teach, clearly shown by his complete lack of interest in the student's opinions.

He does not explain things in class and his homework, lectures, and tests are all different things. He teaches physics and calculus in that class more than chemistry.

Comment:
He is a very smart man but he is not very good at explaining things. Your better off getting a tutor and reading the book rather than sitting through lecture. Also the homework is extremely difficult, I'm not exactly sure how he expects us to be able to complete it. He is a sweet man, I just don't think he understands that we are new chemists.
