This isn't your average SAT prep
Most apps give you a static bank of questions and call it a day. PrepSAT uses recursive AI to build a practice experience that's genuinely personalized to you.
Questions that evolve with you
Ace a basic trig question? The system generates a harder variant that adds constraints, combines concepts, and increases reasoning steps. Struggle with inequalities? It breaks the topic into sub-skills and builds you up.
Inspired by Karpathy's autoresearch — the same recursive optimization loop that trains neural networks, applied to your SAT prep.
