Worst professor ever in my college life!! He is extremely picky and strict. Always stays in the lab watching you do every step of the experiment. Don't ever take his class if you don't have to!

great professor. the fairest professor in grading I have ever met. He is funny at times and his teaching style is fun to follow. His class is the hardest class I have taken here at ucsb.

This professor is the best professor in the Chemistry Department. He is funny, interesting and super super smart. He wants you to learn the material and not just slip by. If you are not a science major don't bother taking him, he is fair but extremely tough. He is extremely helpful, and you would bother to talk to him, you just may learn your stuff

The reason he seems difficult is bc he actually xpects u2learn the material.He won't let u just slide by,bc ur not gonna get n2 medschool that way.He expects&demands a degree of intelligence&maturity,& if u have it,then u'll learn alot.If u read the book,u should do fine on the tests-a 63% is a B-,thats pretty fair.His accent&sarcasm r entertaining

Be prepared to teach yourself.

Please don't take ANY class with this guy. most ridiculous chem teacher i've ever had. quizzes are stupid. tests are even worse tha have no partial credit and ridiculously formatted questions. heavy accent, so he's hard to understand. messy lectures. DONT TAKE THIS GUY! he's smart as hell and expects everyone to be just as smart.

HE's horrbile dont take him unless u want to fail chem 1c. he makes things too damn hard, save ur GPA and take anyone else but him!

This is the worst teacher I have ever had. 1. He is a foreign teacher with a heavy accent and very high and impossible expectations for gen chem students, he is also very disorganized. His tests are the worst judge of knowledge I have ever seen. There is no way to prepare for them. He doesn't have mercy or give reviews.

wow, this professor made me make an account so i could WARN YOU! AVOID THIS PROFESSOR! very unclear in lecture (his tough accent doesnt help.), convuluted tests. I had 2 pop quizzes the week of the midterm! if you cant learn chem by simply reading the book, then avoid this class!!!!

SAVE YOURSELF WHILE YOU STILL CAN! DON'T TAKE THIS PROFESSOR! I mean, he does seem nice and all, but the pop quizzes and the tests r ridiculous. He's asking us stuff that grad students don't even know -_-. He does seem passionate about his work...but he needs to keep it in the lab cuz he is definately shooting over the heads of normal people >_<.

You can tell that he tries really hard in terms of teaching. However he is very difficult to understand, I swear half the time he is speaking Russian. His test are sooo hard and he has pop quizes. He is such a happy guy and nice but this just isnt the class for him

you cant understand anything he says. u have to concentrate so hard on the words that hes using that u dont listen to the material. his tests are ridiculous and you dont get a cheat sheet

I do not like him and his tests are ridiculous

This man is a workaholic. He tries much harder than the average professor to teach us and he gets to know us really well.

Be prepared to work! You will learn a lot but DON'Y come to class unprepared, or his in class oral quizs will make you look like an idoit. He is helpful, but expects a lot.

As many have said before me, this class requires a lot of work - if you're stupid don't take this because you will do poorly!

must prepare to work very hard for this class...his handouts instructions are not always clear though (for data analysis).

Kahn is the worst professor in the chemistry department. On top of his ridiculous ways of teaching, he cannot explain the material clearly and in addition to all, he is a ****. Don't ever want to see his face again, and just because he teaches so many courses in the chem department, I am changing the major.

He is one of the greatest teachers in the chem department. I have taken 4 classes with him and about to take my fifth and I am looking forward to it. He works you hard, but it helps you retain and learn the information. For those who think that he is a bad

Excellent professor. Earned his Ph.D. in one of the best research groups in the country and definitely knows his sh!t. Only the weak and feeble minded dislike him for their inability to comprehend advanced human logic. Basically, don't take his classes if your an idiot.

Dr. Kahn is the hardest professor in the chem dept. I can also say that I have never learned so much in my life. We learn practical skills through lab, but in this class with a HUGE writeup due weekly, it gets overwhelming. He is great, hard, but great. If you are willing to work, take him.
