My math teachers at two different high schools often had library passes ready for me on non-test/quiz days. All I had to do was hand in tomorrows homework assignment today. I had to do all the questions, they wouldn't tell me what cherry-picked questions would be assigned. Worked out well to have me not distracting classtime but I never got any encouragement to continue into advanced maths. My freshman college counselor told me all my prerequisites had been satisfied in HS, don't bother taking more maths. 18yo me was happy to hear it. Meh.
