The size of the classes at Berkeley has always had me scratching my head for decades now.
"I found it really difficult to balance CS61A (a massive class of 2000) with CS169A (still a fairly large class of 350), since 169A required a fair bit of work in writing quizzes/exams (5 quizzes, 1 exam), grading open-ended homework assignments, and staff management."
I knew people who went to Berkeley years ago, and was shocked at the class sizes.
I've worked with Berkeley grads, and besides constantly signaling they went to Berkeley; I wasen't impressed with their abilities. (That goes for all the fancy schools though? All the ones we are suspose to be wowed by.)
Then again some of the guys I worked with whom really impressed me were college dropouts, or mainly self taught.
