The problem sets are great and probably worth the price, but the lectures become very hard to follow after week 3 and the discussion forums are very disorganized - its hard to find useful information. Some of the lectures have slides available, some dont; some of the lectures have somewhat-useful subtitles/transcripts, others have incomprehensible garbled messes (I dont know if theyre machine-generated or just transcribed by someone with no understanding of the material/vocabulary - logarithm != algorithm!).I really like the problem sets, but some of the lectures are pretty rough, just a guy talking in front of some pseudocode for 10 minutes. The instructors seem friendly and engaging, though.
