Reviews of professor Charles Garrison

Rating: 1.0/5, difficulty: 5.0/5
 Doesn't know what he is talking about half the time, very condescending. Everyone in our lab was aware of his attitude anytime you asked him a question about the lab. Only okay thing about his class is he drops your lowest lab. Will also kick you out of lab if you don't have your pre-lab completed. Also, half of the labs were worksheets.

Garrison can be extremely rude and has NO clue what he is talking about. I could not count the amount of times he said he does not know what hes doing. He does not give you clear information for your lab quizzes and will mark you off for the same answer your lab partner got right, and will not fix nor explain. Somehow still passed, but he sucks.

This professor is really helpful if you have questions. He was always available for office hours before each lab so that we can get any questions we had answered. During the lab, he would always check on each group's progress and made sure everyone understood the experiment. Best chemistry instructor I've had.

Passive-aggressive. I emailed and asked for help finding the lab manual days before the class, and he replied "What's this Wednesday's lab? Measurements. Can you find that Measurements PDF and open and read it? Everything you need for this lab is found there. The lab manual is obviously separate PDFs. Let's see what you can do with it.
