He teaches the concepts clearly and we learn how to think critically in his class. I feel like he is the only teacher that taught me science, and other teachers are not as good.

Once you get over his harshness, you will find that he's probably one of the best science teachers you will ever have. Lectures are clear and concise, and with a bit of studying his class is relatively easy to get at least a B in.

Mr. Lee is an excellent chemistry teacher. He is the toughest teacher in chemistry at Irvington, but fair. His clarity of instruction, and course layout makes sense. He provides creative tension to make sure all of his students achieve the best that they can. He is not afraid to praise the students who achieve good results.

Mr. Lee is a very knowledgable teacher who really drills students hard. It's hard to get the grade you want, but you leave the class better prepared. This is personal but, even though I learned from the experience, the class dropped my self-esteem for a long time and I regretfully still panic when I think about it. But talk to Mr. Lee outside of class, he'll prove to be much more warm and approachable (:

I didn't go to Irvington, but he was my tutor for honors chemistry, and he was absolutely amazing. He has a bit of a Chinese accent but nevertheless, his lectures are clear and concise.
With his help I got an 800 on SAT chem.
(the easy, exam difficulty, and textbook use are just random ratings. I had to rate them to post this.)

I had Mr. Lee last year for AP Chem, and I can tell you it's hard. But it's manageable and I barely passed with an A. He trains you really well for the AP test and even though I wasn't the smartest kid in chem and I had trouble with a lot of the concepts, I got a 5 because he just constantly drills you and eventually you get pretty good at it from sheer practice. The end of the year is really chill and btw, Lee is an epic rapper :P

Mr. Lee is very clear when explaining. I love his teaching style: expecting students to pay attention and self study the help sheets he gives out. His test are quite difficult; however, he does curve the score to the 2nd highest or 3rd highest grade so if everybody failed a test, grades would not plummet as much as they could have.

He's not a terribly easy teacher, but he knows how to teach students. He asks you to print out help sheets and they /do/ prepare you very well for his test and the AP test. His tests are mostly based on AP questions from previous years, so they're pretty difficult. He's really strict, but he's a very efficient teacher (and even cracks a joke once in a while)

Strict/harsh (very much so), but knows exactly what he's teaching. Teaching is crystal clear and concise, and help sheets are gold. People think his tests are hard, but if you pay attention to what he's saying in class then you'll know exactly all you need to know (not a bit more, nothing less)to ace his tests and the AP. Coaches you very well for the AP test; all the studying I did was cramming for 2 hours the night before exam. Still easy 5.
Nice guy. Fun, not mean/hard as people say.

Mr. Lee is a terrible teacher. He gives ridiculously hard tests, and treats students unfairly. During class lectures, all he does is barks his "help sheets" (lecture notes) out loud.

in regards to my earlier comment. he isn't rascist, it was because i showed up late to class every week. i was mad when i posted that. anyways, you'll pass the class if you do all your homework, but if you miss even one assignment, then your grade will suffer.
