Getting the most out of a CS degree?

Henry writes: "In September I start on a CS-type degree course. I am probably a fairly typical newbie programmer, in that most of my knowledge centers around scripting and high to very high level programming. Apart from the obvious — write lots of code — what can I do in the coming months to maximize what I get out of this? There's much to choose from: languages, concepts, mathematics and so on. From previous stories I know that many Slashdotters have strong opinions on the failings and weaknesses of university courses and students, so please feel free to let it all out."
