Receive a composite score and separate Reading & Writing / Math section scores — on the same 400–1600 scale used by College Board.
Per-Topic Accuracy Breakdown
See exactly which topics you aced and which ones need work — Algebra, Geometry, Craft & Structure, Information & Ideas, and more.
Adaptive Module Format
Module 2 automatically adapts to your Module 1 performance — harder if you did well, easier if you struggled. Exactly how the real SAT works.
Time-Per-Question Analysis
Find out which question types are slowing you down. Time tracking helps you pace yourself for test day.

Student score improvements after PrepCool prep:
Students who started with this free test
I took the free diagnostic and immediately saw where I was weak — Advanced Math and Craft & Structure. Focused my prep there and went from 1210 to 1480. The score prediction was only off by 20 points from my actual SAT.
Rishit Agarwal
The diagnostic showed I was great at Reading but struggling with Algebra. That clarity was everything. I knew exactly what to study. Ended up with a near-perfect score.
I'd never seen the Digital SAT format before. The free test was the most realistic practice I could find. It prepared me mentally and showed my baseline — I improved 370 points from my diagnostic.
