Professor Gainer is super kind and I enjoyed taking his class. It wasn't super easy, as the ochem classes are typically not, but he was easy to communicate with and receive help from. I recommend any class that he is teaching especially since they made me excited to learn more about ochem and the field.

109C is a TOUGH class. Taken summer of 2021, last online quarter due to the pandemic. The class was graded by weekly quizzes, 1 final exam (worth 2 quizzes, and same difficulty), HW, and class participation. If you spend the time to READ THE TEXTBOOK/watch lectures, you can do well. Gainer is fair (not easy), and available for many OH. Small Curve.

Took this class during the summer 2020. He made sure there was a final and did not curve the class. Only dropped one quiz even though syllabus said two (very misleading). Quizzes are hard and based on videos and what he says. Wish he was more understanding. Spring quarter 2020 he didn't give previous quarter a final AND curved. good luck

I had Gainer for 109C and for Chem6AL. I thought he did a really good job transitioning the courses to online learning on such short notice. Both classes require a lot of hard work, but he was always willing to answer questions. Lab was only miserable because I had an awful TA. I have had Bruice, Read, and Gainer and Gainer was my favorite.

He was able to adapt to online much more quickly than most professors amidst the pandemic. Watching the videos is really important and the weekly quizzes were kinda okay- open book doesn't make it easier!! Pay attention to what he emphasizes because it's usually quizzed on. He's purposely difficult to get you to learn a lot, especially 6AL and 6BL.

Gainer started off as just seeming like a tough grader on quizzes by marking down on any small issue even if it had nothing to do with the problem. But about 5 weeks in the lecture videos started getting to the point where he was just reading out of the textbook, not breaking things down, which really put a bummer on biochem for a lot of us :( GL
