I've been grinding AMC 12 problems for about three months now and I'm stuck in this frustrating 72-84 range. I can handle most of the algebra and precalc stuff fine, but geometry and combinatorics absolutely destroy me every time I sit down with a practice test. Last week I went through the AMC12 A 2025 problems and got completely wrecked by anything past problem 15.
My goal is to hit 100+ so I have a shot at qualifying for AIME. I'm a junior with maybe 8 weeks left before the actual exam. Right now I'm doing about 90 minutes of AMC 12 practice test work per day, but I feel like I'm just spinning my wheels on the same mistakes. Someone in my math club mentioned drilling topic-specific stuff, so I started working through AMC12 Combinatorics and Probability 2 practice sets. Is that the right approach, or should I just be doing full timed AMC 12 sample test runs?
Would really appreciate hearing from anyone who's made a big score jump in a short window. What actually moved the needle for you?
