The contents aren't too difficult, but you should expect devoting a lot of time in homework assignments, which is like a small project each. Attend lectures definitely saves your time.

Dr. Kahn's classes are VERY HARD but his material is always interesting and he constantly pushes students towards harder concepts. If you really try and work hard you will succeed. Please go to his office hours if you need help. He is very kind and supportive, even if he may seem intimidating. DO NOT CHEAT OR SLACK OFF IN HIS CLASS

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

He will make you want to give up on college and/or life even though you are about to graduate.

He's passive-aggressive and doesn't grade fairly. Some students answered the same question essentially the same way and one got no points and the other got full credit. He will kick you out of class for using the solutions as other students cause he considers it cheating. His tests are on things he barely covers.

Get ready to do tons of self- study

If you're looking for an A but not willing to work day and night, avoid this man at all costs. Change to biochem in the bio dept if necessary. He is a great professor if you want to learn difficult concepts in great detail. His theory manuals sometimes get difficult to keep up with. Heard rumors that he's mean, but he's always been very kind to me.

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

the guy should be fired for abusing students, UCSB admin I hope you are reading this and this guy needs to go. There are plenty of good prof. out there except him, no direction in class, mood points, disorganized, and does not know the content but pretends that he does. A complete joke, who hired this guy, he needs a class in manners.

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.

Professor Kahn is a very difficult teacher. He's also the only teacher who will give you access to concise explanations of extremely complex and theoretical material. You are not disillusioned if your reason for taking his class is to have an opportunity to use your knowlege set to look deeply into chemistry. You are if you think A+ is ab initio.

I was enrolled in the biochem lab series with Dr. Kahn for the entire year (3 quarters). He is VERY TOUGH and my mental health was the lowest it has ever been. However, you do gain A LOT out of this series. He always challenges you and pushes you harder than any professors ever will.
