He is a very good lecturer, very smart (he is a double maj in aero engineering and physics, summa cum laude in both degrees). He's caring but also intimidating. He expects you to work hard, and there are many requirements in his Physics 6A class, especially when he teams up with Dr. Wallny. His tests are pretty challenging. Please do all the work and you will benefit much from him and his class.

I dropped his class (and aced 6A in the summer anyway), but also I was reminded that classes are like jobs; if you don't want to get fired or to fire yourself, you have to do the work. If the work is too much, don't put it on your plate; you'll end up not doing well. Take it sometime else.
