Everything you've jotted down on individual questions, compiled in one place. Add notes from any question's detail view — you can add as many as you like per question.
KYJ-SAT is a full digital SAT Reading & Writing and Math question bank with real spaced repetition, adaptive mock exams, and a Bluebook-accurate testing interface — built because the official practice material ran out and studying for it shouldn't cost a subscription.
The tour takes ~2 minutes and walks through the real tabs and buttons, right here in the app. Stuck on a specific page later? Press ⌘K / Ctrl+K and search "help" for a focused tour of just that page, or "shortcuts" for the full keyboard reference.
Four features that are easy to scroll past — each one makes the rest of the app noticeably better.
Every question has a "Rate it" chip — a 1-10 Geometry-Dash-style scale from everyone who's answered it. A minute of tapping makes the difficulty label better for the next student too.
Skill mastery, a trend signal, and a missed-question digest pulled straight from your own history — the fastest way to see what's actually going wrong, not just what you haven't finished yet.
Opt-in experimental settings — offline mode, custom keybindings, choice-count drilling, strict timing, and which Browse filters show up. Most people never open this tab; a lot of them should.
Save, name, and reuse a Test/Practice/Mock Exam setup instead of rebuilding it every time — browse community-made ones too, sorted by likes, with a Recommended badge on the best of them.
The short version, and the person behind it
This started as a personal program where I, noting how terrible college board question banks are formatted, decided to make my own program to keep track of questions. While working on them, I continued to add new features that are conducive to preparing for the SAT more effectiely, and it eventually reached my friends' hands.
Every Reading & Writing and Math question from the official college board question bank, with a handful of features to practice systematically.
Weak-skill bias, FSRS spaced repetition, and a per-skill mastery breakdown — not just a pile of questions.
No paywall, no ads, no account required to use any study mode.
