by James Lu — Skoolmakers Rating

SAT Prep is James Lu's free community for students preparing for the SAT, focused specifically on the Desmos graphing calculator and grammar. It opened in June 2025 and reached 30,700 members quickly, with 11 courses across 145 modules and around 9,180 posts. The notable weakness is staffing: two admins for 30,700 members is the thinnest ratio in this batch, so questions get peer answers or none. The narrow focus is the strength. Desmos is allowed on the digital SAT and using it well is a genuine, learnable edge that most general prep material treats as an afterthought. For a free resource aimed at students, who are the least able to pay, that combination is worth something.

❓ FAQ

Does it cover the whole SAT?

No. The focus is Desmos and grammar, which is why it works as a supplement rather than a full prep course. Desmos in particular is a real edge on the digital exam that most general material skips.

Can you get help from the team?

Barely. Two admins cover 30,700 members, the thinnest ratio in this batch. Treat it as a resource library with a peer feed rather than a tutoring service.

Is it free for students?

Yes, entirely. That matters more here than in most categories, since the audience has the least ability to pay for prep.
