AI-powered adaptive practice, real diagnostic insights, and expert-level explanations — built for students who want to score higher, faster.
Correct answer pushes you harder. Wrong answer finds your level. Starts at medium, adjusts every question.
Numeric answer questions — type your answer just like on the real digital SAT. No multiple choice crutch.
Every question explains why the correct answer is right and why each wrong answer is wrong — with named trap types.
See your level move in real time. The header shows whether you're trending up or down after every answer.
Math, Reading, English/Writing, and ACT Science — all adaptive, all with explanations, all verified.
Peak difficulty, average difficulty, longest correct streak — see exactly how your session went.
After 20 questions, the app tells you your #1 recurring error trap — sign flip, misread question, wrong formula — and drills exactly that pattern to break the habit. No other app does this.
Difficulty-weighted score prediction — the same model the real SAT uses internally. Not a simple percentage. Tells you "estimated 1180–1240" based on which difficulty levels you actually passed.
Each question shows your target time. After answering: "You took 3:10 — 1:40 over target. On the real test, this costs you 2 questions." Trains the timing skill that separates 1400 from 1500.
Drill only Quadratics. Only Inference questions. Only Conflicting Viewpoints. Each sub-drill has its own CAT engine and a mastery signal — 3 consecutive D4+ correct means you've nailed it.
One-time baseline test covering all sections and all difficulty levels. Outputs your theta score per domain, top 3 error traps, estimated SAT and ACT score range simultaneously, and a ranked study plan showing which subtopics will move your score the most per hour of practice. Re-diagnostic every 2 weeks shows your trajectory.
3 correct in a row? Timer speeds up, difficulty jumps to D4–D5. Trains the composure that separates practice scores from real scores.
Weekly email digest: sessions, score trajectory, weakest subtopic, time practiced. Parents who see progress stay invested longer.
SAT tutors assign specific subtopics to students. Track every student's results. Bulk licenses for agencies at one monthly rate.
