Not quite true; students often study some math along with some CS and those two classes are considered "core" classes in math and CS respectively. But yes, I know that the "analysis" side of math is not particularly close to CS. I give calc I and II as an example of an ostensibly high quality core math class that one can take for credit at an ostensibly high quality institution. My question is, where can I do core CS classes for credit, in the way that I can do core math classes at extension.berkeley.edu?
