CruxStudy › Free tools
Small, single-purpose tools that answer one question properly. No account, no email, nothing to install, and they all run entirely in your browser.
Turn questions correct into a scaled score, and see exactly how much the adaptive second module changes your ceiling.
Open →Enter your PSAT section scores and get the National Merit Selection Index out of 228, plus what ten more points in each section would be worth.
Open →Convert in either direction using the official concordance, with the full table and an explanation of what a concordance can and cannot tell you.
Open →Enter a test date, a current score and a target. Get a week-by-week plan, and a straight answer about whether the target is reachable in the time left.

Untimed, about fifteen minutes, and it scores every content area on your exam.
