Quarter Taken: Summer 2017 Submitted Aug. 6, 2017 Grade Received: A

Took this class in 2017 Summer Session A. Amazing professor and amazing person. He deeply cares about his students and performs well above and beyond his duties as a professor. His explanations are clear, but they tend to be mildly obscured by his accent. He has a high expectation of his students, which he tells to all his students before the class begins, so effort is required to do well in his class. He has a 1-2 question daily preview due every day and a 3-5 question self evaluation due every Friday. Before every major test, if so requested, he will make a practice self evaluation that is 10 questions long. Though only 2 questions are due, I highly recommend completing all of the questions, since they are all relevant to the test. Overall, he's a great professor and I'm lucky to have him as one of my firsts.

Edit (6/7/2018): Professor Lin was one of my first professors. Now that I've had other professors as a comparison, I believe that the praise I gave to him is severely lacking to what he deserves. Quite honestly, Professor Lin performs well above and beyond other professors that I've rated 5/5 on Bruinwalk, so he should really be getting something like a 6 or a 7 on the same scale. I cannot stress how fantastic of a professor Lin is. I would highly encourage you to take a course with him if possible.

I am a student from China. I enrolled in this course to be qualified for the F1 visa, in order to do travel study in US this summer. Mr. Lin makes chemistry so interesting and exciting. I enjoyed very much his teaching style: clear, logical, rigorous, and humorous. He seemlessly connects his lectures, problem sets, and self evaluations to modern research publications. In fact, I am so proud of myself that I can predict in the final exam the HOMO-LUMO transition of a dream molecule "cyclic polyyne C10" and prove that quantum tunneling of 2H in palladium electrode by itself cannot trigger cold fusion. Going to his "quantum paradise" (class meetings and office hours) becomes the priority and focus of my everyday activities. Mr. Lin is very kind and generous. Since the office hour 12-1 follows the class meetings immediately and is popular, he frequently brings some snack to the office hours, so that we will not get too hungry. Since the review sessions are 4-7pm (in fact, it ended at 8pm) the two nights before the final and all class went, he treated the class pizza and snapple during the break, so that we will not get too hungry. I hope to become a professor in the future and he is my role model. Perhaps I will use his chemistry jokes in my teaching, too. They are so funny :) The only complaint I have is: since this course is so overwhelming and there is always homework due in every class meeting, I could not do any travelling over the past six weeks :( I may come back next summer to take his course again.

We just finsihed the final exam this morning. I am an EE major. I took this course merely to fulfill my course requirements so that I can graduate. But after six weeks, I am thinking about the possibility of pursuing quantum mechanics in the future. Prof. Lin is a very kind, caring, and passionate professor, with a good sense of humor. He integrates modern chemistry research such as quantum teleportation, quantum eraser, quantum imaging, quantum computing, quantum corrals, molecular cascades into the lectures, homework, and exams. This is the best course that I have taken so far at UCLA. But be warned, Prof. Lin imposes high standards and has high expectations towards his students (and even higher standards towards himself). Five homework due per week: 4 daily previews and 1 problem set. It will take you an enormous amount of time to study, think, and do homework. But you will learn A LOT! Very strongly recommended. Take his courses whenever possible.

I was in Prof. Lin's Chem 14A Summer C 2016. I have learned a lot from this class and am fortunate to have Prof. Lin as my first college professor. He taught me so much, not only chemistry, but also about how to work hard and smart through true understanding, how to bring myself up, being an academic family, the importance of attitude and kindness. I am seriously thinking about changing my major from pre-med to chemistry. But be warned: his expectation is very high and workload very heavy (daily previews or weekly problem sets due in each and every lecture and TA discussion).

Quarter Taken: Summer 2016 Submitted Aug. 9, 2016 Grade Received: A+

I took the class as an international high school student, and since I've got an A+, there's nothing you should worry about.

PRO:
-- The lecture is largely clear. Occasionally some contents aren't explained with clarity, but with a little bit of research you can figure it out yourself, and I don't assume any professors can make everything in his/her class clear.
-- The professor is VERY considerate and cares DEEPLY about his students. Let me just say this, you're unlikely to encounter another professor that cares this much, especially for an introductory course. Prof. Lin is very responsible and carefully reviews every piece of homework that we submitted. The grading is fast. He remembers every student's name. He replies his email generally within an hour (it's like he never sleeps). And yeah, those rumors are true, he does provide awesome Asian snacks, pizzas and Subways during tests and review sessions.
-- The course content is very challenging at the start, especially with the Schrodinger equation part. But if you fully grasp the essence of wavefunctions, then the rest of the course is just a breeze. Of course, even though the course only has Math 31A as its requisite, you need to know your stuff about integrals and Taylor expansions. A little bit of knowledge of differential equation would help, but not much.
-- Even though the content is harder than usual, it's not very likely that you'll get a grade below A-, seriously. Prof. Lin goes through the contents for so many times we can even remember his tones when delivering the derivations. Plus, he presents practice tests, which are very similar to the real ones.
CON:
-- He carries a somewhat obscure accent, similar to Chinese accent but not quite. Anyway the first few lectures would be miserable, just because of his accent. But you'll quickly catch on.
-- Because Prof. Lin repeats the contents for so many times since he wants to make sure everybody understands what's going on, he usually lags quite a bit. By the time the course ends, there're still around 25 percent of materials that weren't lectured at all. This can be frustrating, but the good part is you won't feel confused at all about what you've been lectured on.
-- Workload is relatively heavy. There're previews due every day from Monday to Thursday, each one featuring one to two questions; usually the contents are way ahead of what's being taught in the lecture so you really need to read your textbook. The questions are not hard, though. There's a problem set that reviews lecture contents with around 4 questions that's due every Friday. The problem set is even easier except for the last one, which is very math-heavy.
-- Attendance is mandatory, but I haven't adapted to college culture of skipping classes yet, so this isn't much of a problem. Also, you can skip at most 2 lectures or discussions.

RECOMMENDATION POLICY: I have never seen a professor that OFFERS you recommendations, but that's what he did. Basically every lectures he talks about how you need to work hard, and if you get satisfactory grades, he'll personally write you a very LONG recommendation letter, one that's optimized based on each student. So if you want a recommendation that's actually ABOUT you and is actually useful, go to his class.

GRADING POLICY: One midterm and one final, each for three hours. The higher one constitutes 32 percent while the low one constitutes 29 percent. There's 18 percent for previews and another 18 percent for problems sets, so do your homework. The rest of the points are assigned by TA based on your "participation" in discussions. There're 2 bonus points if you attend all the classes (those 2 occasions don't count) and pend all homework on time. You need 98 percent for A+ and 92 percent for A.

I'm still exploring school options but Prof. Lin literally deepens my appreciation of UCLA. He's a very hard-working professor, so choose him whenever you can.

DON'T TAKE LIN.
HE TAKES QUANTUM MECHANICS TO A COMPLETE NEW LEVEL YOU DON'T EVEN WANT TO UNDERSTAND.
YOU'LL NOT GET GET BETTER THAN A B UNLESS YOU'RE A NERD AND LIKE MEMORIZING PROOFS OF SCHRODINGER'S EQUATION.

Prof Lin's class is extremely hard -- much harder than it needs to be. He often lectures on irrelevant information, and I left class more confused most days. I had friends in other 20A lectures who were learning completely different information, ours being much harder.

He is incredibly difficult to understand because of his accent so be prepared to have to decipher his lectures.

He doesn't really teach, just kind of throws the information at you for you to figure out on your own. If it wasn't for the TA's I don't know how I would've gotten a B-

Best professor ever! He is very passionate about what's he teaching and is also very caring for his students. He makes quantum mechanic interesting and easy to understand. Definitely recommend taking him. You will not regret it. It might be hard to understand him at first, but after awhile you will get used to it. Tip: Attend all of his office hours. Very helpful and you get good Japanese snacks too!! Not a hard class at all!!

He is a great professor and I highly recommend him. Though he is really busy he tries his best to help his students. Dr. Lin is also very difficult. He expects a lot out of his students. But if you show him that you are trying hard then he will help you where you need it. Just study diligently in his class and you should be okay.

Basically, Prof Lin is a really nice guy. the problem i had with him is that for chem 20 A we're supposed ti be learning basic chem stuff. With professor lin, we go into lots of detail on upper division subjects. Thats well and good if you want to study chemistry, but if like me, you are taking this class because your major requires it and you do not like chemistry, the material covered in the class is completely useless to you.
