LSAT prep materials are widely available, but you should know the LSAT isn’t a subject matter test, in that it’s not about law directly. It’s essentially a reasoning test, and the questions are pretty challenging, though if you’ve taken discrete math it will probably come more naturally.

Khan Academy’s LSAT prep is actually fantastic. I used it for my LSAT prep and iirc my best score was a 168 on my third/final test.
