Frankly speaking 151A are in general fairly easy, and are supposed to be useful. Unfortunately, we are behind the schedule almost since day one, and this professor never modify the schedule and homework accordingly. This means that from probably week2 and on you need to figure out almost everything on your own to solve the homework problems, because by the deadline, you probably haven't learn anything about these in class. Note that the homework score is about 35% percent of your total score and if you screwed up your homework you screwed up everything... The exam are not that hard, but the hard part of the exam are actually not related to the course material itself, it is more of like testing your general math ability which is kind of unfair, cuz these scores will not 100% reflect your actual actual performance in this class. He does post lecture note, and his lecture is basically reading and copying these lecture note which an iPad can do. But I guess this is one of the few helpful things. In short, my experience with this class is almost like "studying the lecture note by yourself" because you need to finish the homework ahead of the lecture and by the time you sit in the lecture, it's a little waste of time to see him copying everything on to the board.

Good and nice professor, especially nice that he posts his lecture notes. Class is very straight forward, but you have to put the work in. Homework is a large part of your grade.
