He has 4 exams in one single quarter. He sometimes has class on Monday and tests on Wednesday about what you just learned on Monday, which is IMPOSSIBLE to do especially for Ochem. You must get help from your friends who previously had the class to get good results. If not, you'll probably get a C or lower. He is the best among chem 109 though.

Lewis is a great professor, despite the subject's challenges. He equips you with essential tools, you have to choose your own approach. Some require more time to grasp topics, while others need less, but success is attainable with effort. Dedicate as much study time as you need, utilize textbook, and attend office hours.

5% people got A/A+ and he said the class did pretty well and refused to apply any curve.

He is definitely a solid professor, I just feel he's a little overhyped. His lectures are clear cut--he teaches out of the book and you know what it is that he will be covering each day if you do the homework. He answers questions well, but I just feel that he can get stale. Quizzes/tests were challenging very doable. Preferred Gainer.

Hardest chem class I've taken, but that is partially due to my workload this quarter. Lewis is undeniably the best Ochem professor here, but it's still ochem. You WILL fail if you don't put in the work. As everyone has said before, DO THE BOOK PROBLEMS AND GO TO OFFICE HOURS IF YOU NEED HELP.
