This class is called COM SCI M51A or EC ENGR M16 depending on which department your in, they are the same class just with different names.

Most of the reviews for this class are under this professor's EC ENGR M16 page!

I really don't understand how this professor has such good reviews. A lot of them say that he is a very 'nice' and 'helpful' guy, but in actuality he is anything but. I don't even believe we had a single thing to hand in until week 4, which may sound nice but really isn't, as this is a topic that you really can only begin to understand through actually doing it. We only had about 6 things total due this entire quarter, including 2 exams and the final. During our final exam (which we had all of finals week to complete), the professor kept on changing his mind on certain guidelines in a very unclear way, and students rightfully kept on asking him to clarify what was and wasn't allowed on Piazza. In response to students asking questions, the professor essentially shut down Piazza for the final exam, by forcing you to read through 50 messages of his before asking a question, none of these messages which seemed to really clarify the questions at hand.
Also, good luck making friends in this class to help you out with understanding things, as the professor has the strictest collaboration policy of any that I have seen so far in my time at UCLA. If you are caught collaborating on even a homework in any way, you get an immediate 0 in the course followed by a report to administration.
All in all, I would recommend taking this class with a different professor.
