Don't take him, switch to biochem MCDB or take biochem at another UC. Always thinks someone is cheating, too much homework and assigns before midterms. Made us read a article on wikipedia to find the mistake when it wasn't there as a quiz question. Extremely condescending, started off with 44 students and about 16 were. Avoid him at all cost plzz

Get ready to do tons of self- study

Kahn is by far the worst professor Ive ever encountered. 3 quizzes/week on useless material. Intent on throwing students off, last minute updates to assignments, quizzes, exam structure. Abused his power to intimidate students. Hardest class Ive taken for only 3 units. AVOID AT ALL COSTS, THIS PLAGUE OF A HUMAN WILL RUIN YOUR SEMESTER AND BEYOND

It's been a nightmare I wish I could wake up from. If you think about pre-med, DO NOT take his class! If you need biochem for graduation, I recommend taking it at another UC. You will thank me later.

Kahn makes you feel dumb. He gives a lot of HW that has almost nothing to do with the course material. Tests are really hard and he gives pop quizzes. Avoid him at all costs.

This professor has an encyclopedic knowledge of the subject, and that's good, because this course is intense (of course it is - it's an upper division Biochemistry course taught on a severely compressed schedule). Do the work and participate, and you will get a good grade.
