If you want to get an A and make your GPA look all nice, take this class, because no matter how badly you suck at physics and math, you can still get an A by studying the examples for the test.

Stares at the board and mumbles. Accent isnt as bad as people make it be. If taken in high school or elsewhere you should be fine. If not, then beware. Lets just say I didnt take the 2nd semester with any other prof because I would fail miserably due to my lack of knowledge from the preceding semester. Chinese>he will love you. if not>he might.

He is a smart professor, but you have to study on your own all the time. Work hard and don't cheat on yourself, you will be fine. It is not difficult to get A if you try.

I highly recomend people who aren't good in physic to not take this class.Doesnt teach that well so you've to do a lot of studying ON YOUR OWN.His grading his fair.Do all the hw/lab and you should pass even if you fail the tests.Labs are quick n easy since he guide you thru it. Very funny and nice professor. Altough not very helpful w/ hw question.

Ok, so I took his online course with the intention to get an A (as always), but found the class to be extremely difficult. For some reason, the tests were on a completely different level from his lecture. He would expect us to just do well by knowing certain problems he assigns, but it didnt turn out that way afterall. Took only his class that sem.

His class is easy as long as you review the study guide. All questions are selected randomly from it. His lecture is clear, but his heavy accent may bother you. Randomly check attendance and would deduct points for it. Memorize the study guide because he will redistribute the points for each mistake if there are so many perfect scores.

It's not like you have a choice if you need 31A & B for your major. Wai Min maintains a very relaxed and convivial atmosphere, but you will learn ZERO from his lectures. He assigns the more difficult problems for hw, but the tests usually come straight from assignments and examples. That's the trick--master the hw and the test is a piece of cake.

I took Prof. Liu's Physics 2A class in the Fall of 2015. He really wants his students to succeed, is available during office hours and occasionally gives EC. Make sure you do your HW, as the exam questions are HW questions but with different numbers. The book helps a lot. Read it before class, then listen to his lectures.

As someone who has never taken physics prior to this class and is not particularly good at it, it's vital that you read and do the problems that he assigns. Study the problems. All test questions come from the problems with minor variation. Be sure to have perfect attendance and take the lab reports seriously. You'll be fine if you follow this.
