Questions are drawn from the four SAT Math domains and balanced to match the official proportions — Algebra (≈35%), Advanced Math (≈35%), Problem-Solving & Data (≈15%), Geometry & Trigonometry (≈15%).
Every question is a fresh variation of a real SAT-style problem. Missed questions get a step-by-step solution and a follow-up variation.
Practice mode (default): endless single questions, checked instantly, drawn from every domain with the real test weighting and at any difficulty. Miss one and you get the how-to-solve plus a second variation. Every answer is saved as you go — so stop whenever you like. Exam mode gives you a fixed-size set to work through first.
1️⃣ Answer every question.
2️⃣ Submit — each wrong answer shows a step-by-step how-to-solve.
3️⃣ You get a variation of that question to try again.
4️⃣ Wrong again? The same instruction is shown and the question is marked ⚠️ to be resolved.
🔗 Every missed question links back to its trunk (the original source question).
🧩 Each exam is graded: Module 1 is the easier half and Module 2 the harder half, and both modules mix all four domains. Short quizzes still cover every domain.
🎯 Practice mode never runs out: questions keep coming at random, weighted so Algebra and Advanced Math appear far more often than Data or Geometry, and each answer is graded on the spot. Mistakes are saved the moment they happen, so the teacher view sees them even if you stop halfway.
