>>16727334 (OP)If it's like an intro to proofs/discrete math/problem solving type class you'll be fine. Those classes are usually piss easy.
If it's a legit real analysis or abstract algebra class you should still mostly be fine those classes shouldn't be too hard especially if they aren't assuming knowledge of sets and proofs and stuff first. That said, it would still probably be a good idea to read through the first 12 chapters of Hammack's "book of proof."
