Berkeley was making all of their lecture videos available to the public until they recently moved to EdX. Course videos from Spring 2015 and prior (going back as far as Spring 2010) can be accessed here: <a href="http://webcast.berkeley.edu/series.html#c,d,Computer_Science" rel="nofollow">http://webcast.berkeley.edu/series.html#c,d,Computer_Science</a><p>I have been working through the cs core classes (61a/b/c) by following the syllabus from the semester corresponding to the videos for reading and homework assignments. A google search of course number and professor's last name has been the easiest method of finding the course website (not all of them use the Berkeley course page).
