Professor Lin is one of the best professors I have ever had at UCLA. He demands a lot out of you, but its a fun challenge. He helps students a lot and holds office hours numerous times throughout the week. During the midterms he provided snacks and drinks for students. This class was probably one of the most useful classes I have taken. If you like math, then take this class for sure. I seriously think learning quantum mechanics is a very useful tool that I can use later on in my career.

A++ prof.....he was high demanding but u can learn a lot...

one of the best professor you can have in UCLA.

go take him. the class may be time consuming, but he gives his all to help you learn.
(+ who else buys students pizza, chocolate for valentine, cookies from japan, holds office hour/review session on weekends, sends you an email to give compliment on your success in class?)

Prof Lin is nice. He requests for student's photos at the beginning so that he can remember them later on when they ask for a letter of Rec. (If you ask him later, he will ask for your resume, copy of your transcript, and the essays you wrote for whatever program you are applying for.)

He tells you everything he expects from you.
Past year exams are very similar to current year's practice exams, and past year's practice exams are very similar to current year's exams. You can do well if you just do all the work he gives you.

He offers a lot of extra office hours, weekends, weekdays, late nights.
You have to give him slack for sometimes being a little late to his OH because he's always very busy. A friend and I saw him going back to work in his lab at 4am in the morning after taking a break walking around campus.

Prof Lin is the best professor in UCLA so far..thank him because he made my supposedly unimaginably hard quantum mechanics course to be well understood and easy to follow...he is very concerned with students' learning and success, no professor on earth will do final review/ office hour on Saturday, in fact on Sunday...I admit the homework loads are a lot, but if you just keep track on it, you'll do fine in his class..his tests are reasonable, basically, it's what he teaches in class...thanks for the chocolates, cookies, and pizzas...oh yeah, don't slack off in his class, it will be hard to keep up. If he will be teaching Chem 115A or B, I'll definitely enroll in his class no matter how hard the class is...I really recommend prof Lin to all chem students...Thanks prof Lin!!!!!
