How a Module Works
Every module runs the same five-beat loop. Spot the type — read the problem and name what it's asking before you touch a number. Grab the formula for that type, then study a worked example that shows it end to end. Practice on paper with the sheet face-down, peeking only when you're stuck. Then add one line to your cheat sheet so the topic comes with you on test day.
Practice here is always work-on-paper, then reveal the answer to check yourself — never a tap-the-right-box quiz.

Still to build: partial fractions · set theory · permutations & combinations · binomial. They'll land as modules the same way — spot the type, grab the formula, practice on paper.
Topics I've Built Into My Sheet
Mark a topic once its lines are on your cheat sheet — honest self-check, saved on this phone only.
This tracks coverage, not a grade. A topic counts when it's written, not when it's perfect.
