Things you ought to never do…
Alright, day two – year three. Some advice: it is not advisable to take discrete mathematics without a proper understanding of set theory and moderate experience with formal proofs. Do not mishear your professor and try to make the power set of S a subset of S. It will keep you confused long into the night. I’d also recommend doing some in depth research when registering for a computer science class, because you have about a 50:50 shot of inadvertently being in ANOTHER barely comprehensible MATH class....
