Five steps. One platform. Everything you need from diagnostic to test day.
STEP 01
A diagnostic puts you on the right starting line. After that, each day rolls topics, practice, and vocab into one continuous lesson — no checklist, no decisions, just press play. Step away anytime; Prepiii picks up where you left off and reshapes the plan as you go.
STEP 02
Scratchpad, Desmos, and Prepiii in one place. Sketch your steps and Prepiii draws on what you wrote, names the skill, lays out a strategy, or just gives a nudge — never the answer outright.
STEP 03
Solving once is a start — mastery is reps. Tap Generate Similar after any problem and Prepiii spins up a fresh question with the same pattern: same skill, new numbers.
STEP 04
Every math topic Prepiii teaches lives in one place — not walls of static text, but interactive lessons with live graphs, widgets, and worked examples you can poke at. Drop in any time to read ahead or fill a gap your study plan exposed.
STEP 05
Full-length, fully timed mock exams. Two adaptive modules — nail Module 1 and Module 2 ramps up, exactly like the real SAT. Scored on the 200–1600 scale with full review of every wrong answer.
Soon you'll be able to browse video courses, problem packs, and vocabulary sets created by tutors who've been through the test themselves — all integrated with Prepiii so the AI knows exactly what you're studying.
Structured walkthroughs from tutors who've scored 1500+ themselves.
Hand-curated drills targeting specific question types and difficulty bands.
Themed flashcard decks with spaced repetition baked in.
3,000+ problems. Prepiii sees your work and remembers how you learn. Start free — paid plans include a 7-day money-back guarantee.
