TERRIBLE TEACHER. the reasons his ratings do not support this is because he is FUNNY so people tend to like him. He does blow stuff up and all which is interesting but he CAN NOT TEACH well at all. Teaches rote memorizations rather than trends and does so very poorly. His writing and english also suck. Although the other teacher is bad too so??

Professor Kaiser's class is really easy. No homework, just study the practice tests. He does have a German accent, but as long as you know what "Fe" is, you'll be fine. The experiments keep the class interesting. If you ever need help, you can just ask Andrew and he'll help you. Also, if Andrew has a lab, take it.

This class was just average. Kaiser can be nice and even funny sometimes; the class is fair. The practice exams were nice (and a must-do) and experiments were cool. Getting a good grade could be hard, but Andrew Turner will be your life saver! BEST T.A. EVER. He actually cares for the students, and wants you to succeed. (He likes nachos and candy)

Took chemistry sophomore year of high school so I didn't remember a lot of stuff. It was really confusing because he tends to go quickly and sometimes overcomplicates topics. The curve is a life saver. Do the practice exams and make sure to use the Learning Emporium and go to the review session. Effort will pay off for a decent grade.

First things first, Don't skip class! When he usually talks about space or such there's a high chance that will be on the midterm. In some lectures there's also experiments that will be on the test. He adds some jokes here and there but with the light dimmed down you could get sleepy. To get an A in this class just do the practice tests he has.

There's no assignments, so your grades depend on how well you do on your tests. Memorize the random astrochemistry facts on his slides for a free two points on a midterm/final. That can boost your score up by a letter grade. If you ask him for help, he'll gladly assist you. Solid choice if you actually read the textbook.

A funny German man who knows his stuff. Lectures can be boring, though they are thorough and very helpful. This class is based on 5 exams which includes the final. Each exam has a corresponding set of practice problems which, if you do them and understand them, should land you at least a B.

There are no assignments or homework in this class so your grades are solely based on 4 exams and 1 final exam.

Kaiser's practice exams are helpful, but beware of questions that are answered by paying attention during lectures. His final exam consisted of 50 questions (instead of his usual 30 for midterms) which are cumulative, as about 1/3 of the questions are from the last 2 chapters from the semester, and 2/3 are from the midterms in the past.

It took time to understand him in his Russian accent. He could be funny SOMETIMES. Did alot of examples. If you took AP Chem in highschool, you should be able to grasp the concepts since it's like a review class. Had to depend on a friend who did take AP and practice exams.
