I honestly don’t know what the big fuss was about this professor. He’s a below average professor. I went into this class with huge enthusiasm, which he killed after his first office visit. His lectures simply lack passion, and clarity and are not helpful, I barely went to any after the first 2 weeks of trying. He does not explain it well, if it was not for the MIT lectures up on youtube I would’ve failed the course. He has the tendency of talking to the board and mumbling. I mean, I tried so hard to actually pay attention during lectures but I would space out after the first 10 min. I thought he was a nice guy and went to his office to speak to him about my grades and I swear the man had an attitude problem, I don’t know what it was really. And he was anything but encouraging. He does give a lot of homework though, a lot! On the other hand I don’t think his tests are SUPER hard, I believe they can be harder. 6B is a pretty hard class itself he can’t really make it easy. But if you take his class you’ve gotta stay on top of things, watch the MIT lectures, REALLLY help. He should perhaps watch those videos himself to see how the professors there explain it, crystal clear explanation of the material. Anyway if you’re stuck with him a few pointers that I can give you is ALWAYSS make sure you understand EVERY problem from
a) the practice exam
b) concept tests
c) the examples done in the chapters
d) and the homework problems
NEVR copy down the homework from the solutions manual, although it could be very tempting, it will hurt you at the end.

GOOD LUCK

Oh almost forgot, to mention his positive(s): he does respond back to e-mails very quickly and also he tries extra hard to be funny, the key word is "try"
