May is an exciting month! National MATHCOUNTS is the second week of May in Washington D.C. and our Founder, Richard Rusczyk will be presenting a seminar, Preparing Strong Math Students for College and Careers, on May 11th.

Are you interested in working towards MATHCOUNTS and don’t know where to start? We have you covered! If you have taken Prealgebra, then you are ready for MATHCOUNTS/AMC 8 Basics. Already aiming for State or National MATHCOUNTS and harder AMC 8 problems? Then our MATHCOUNTS/AMC 8 Advanced course is for you.

Summer camps are starting next month at the Virtual Campus in math and language arts that are 2 - to 4 - weeks in duration. Spaces are still available - don’t miss your chance to have an enriching summer experience. There are middle and high school competition math camps as well as Math Beasts camps that review key topics coupled with fun explorations covering areas such as graph theory (Math Beasts Camp 6), cryptography (Math Beasts Camp 7-8), and topology (Math Beasts Camp 8-9)!

Be sure to mark your calendars for the following upcoming events:
[list][*]May 9th, 4:30pm PT/7:30pm ET, Casework 2: Overwhelming Evidence — A Text Adventure, a game where participants will work together to navigate the map, solve puzzles, and win! All are welcome.
[*]May 19th, 4:30pm PT/7:30pm ET, What's Next After Beast Academy?, designed for students finishing Beast Academy and ready for Prealgebra 1.
[*]May 20th, 4:00pm PT/7:00pm ET, Mathcamp 2025 Qualifying Quiz Part 1 Math Jam, Problems 1 to 4, join the Canada/USA Mathcamp staff for this exciting Math Jam, where they discuss solutions to Problems 1 to 4 of the 2025 Mathcamp Qualifying Quiz!

Those are the book I already bought lol. Geo is perfect for AMC 10 and IA is also pretty good.

i finished these books at 2 months old (jk ofc, i am still working on chapter 4 of geo and just started int alg). however, i think most of the int alg is too hard for amc 8 but will probably be helpful for amc 10

I would say to skip Algebra and Number Theory and just straight dive into Geo and C and P, after that go to Inter Alg and Inter c and P then move onto to pre calc and if you want calc

I mean if you want to make AIME then I guess you have to study complex numbers because it is on there all the time for AIME but it might be on AMC 10 it depends I would recommend to do what you are weak at first then move up to the easier topics you know already.

IA is fairly long, and I'll need to do most of precalc, Inter CP and probably Inter NT
I'll take it, but I won't worry about it much

Introduction to Geometry is actually pretty hard, but it provides a solid fundamental in geometry up to AMC10-AMC12.
Introduction to Algebra is good also, can help you get to like 105-110 on AMC10 or 90-95 AMC12 but Intermediate Algebra is necessary to get higher like 125+.
