I built this because I got tired of practice platforms reporting a score to the nearest point when nobody outside the College Board has the equating data to justify the last two digits.
Preptics reports a range with a stated confidence instead 60 after one mock, narrowing to 40 after three, where it stops, because what's left at that point is conversion error and a fourth test doesn't reduce it. The whole method is public at /how-scores-work, thresholds included.
It's free during beta. The interactive graphers at /tools need no account at all if you just want to poke at something. Happy to argue about the statistics in the comments that's genuinely the feedback I want.
Preptics completely personalizes Digital SAT preparation using advanced behavioral telemetry. During practice exams, our system tracks real-time data including tool usage, time distribution, and user hesitation. Proprietary algorithms and AI engines process this granular data to accurately isolate knowledge gaps, predict score outcomes, and build precise improvement plans. The result is a fully dynamic ecosystem that updates lessons and drills on the fly to match evolving student needs.
