Professor Miao is a very fair professor. While his lectures are somewhat monotonous, in that he just went over formulas with few examples, his tests and homework were quite fair. He even dropped the lowest of you two mid-term scores. Make sure that you understand problems from the book and that you review the examples in the book, because that is where he gets his questions. I had to work hard to know how to do the problems in the book, but if you understand those, you should do well in his class. As in any class, make sure that you check you tests when you get them back. On one of my mid-terms for him the T.A.'s mis-calculated my score and I ended up getting 12 points back...I would recommend Miao, just know that it is not cake, but it is not impossible either.

this class has two midterms & one final; professor miao definitely is concerned about student learning, and even offered to drop one of our midterm scores. his tests are really fair -- he usually includes one homework problem of the four problems on his midterm, so you should definitely do your homework and study your notes, as a couple of the questions on the final had stuff in the notes.

Miao's "easiness" is conditional - I have friends who got 95-100 on the first midterm, and others who got below 50. If you've taken physics AP or are pretty familiar with mechanics then Miao's tests should be cake. However, if you're like me and haven't taken any physics in high school, then try to avoid Miao. He sometimes teaches in a way that reviews concepts assuming you know what's going on.
The midterm grade distribution was very abnormal - it wasn't a bell curve, it was a straight line. Some people think that Miao is the easiest professor ever while a relatively high percentage of people dropped out after the first midterm. However, Miao is one of those professors who want everyone to "get an A and become doctors"; if enough people in the class email him, he'll extend deadlines. I completely bombed a the midterm but since he let us drop one midterm scores, I ended up with a B.
