This looks great. My son uses “beast academy” from Art of Problem Solving (https://beastacademy.com/), which is fantastic. But mathacademy looks like it might be a good competitor at the post year 6 level.

It would probably be best to use the AoPS books in conjunction with the site as a supplement.

My observation is that the paper books are unnecessary because the online experience on beastacademy is so comprehensive - and your answers are auto checked. YMMV.
