My 6th grader has started liking maths competitions and wants to do well in AMC8 next year. He got a 12/25 this year, and wants to get 18 next year. He takes Pre-Algebra in school.

1. What books do redittors here suggest for him in his prep for next year, if he solves 5 problems (or works for 30 mins everyday) on competition maths?

2. I see AoPS and Mastering AMC8 by OmegaLearning as popular resources online. While OmegaLearn has free pdf, each AoPS book is ~$60. Can I get used books somewhere? Or any other suggestions?

Thanks in Advance!
