Where did you top out in math classes?
mnemonicsloth: With one notable exception, math seems very easy to me.  I open the book, write down verbatim anything labeled Definition, Theorem, or Lemma, and trace through anything labeled Proof.  There's nothing particularly hard about it -- you just have to make sure you actually do every step listed inside your head.It is a little slower than reading for pleasure, but with practice, I'd say only by about half.I think the primary reason I do well, though, is that I take adderall for ADHD.  Stimulants make it trivially easy to maintain the necessary level of focus, but whenever I forget to take them before a lecture or study session, I'm gnashing my teeth and tearing my hair out by the end.
