How to use this site
If you have eight weeks to your test: work through one category per week, doing every topic page in order. Use the past paper topic guides to find your weakest areas, then loop back to drill them.
If you have two weeks: take an official practice test, identify the questions you got wrong, and use the topic guides to drill exactly those skills. Don't try to cover everything — focus tight.
If you're starting from scratch: begin with SAT Algebra or ACT Pre-Algebra, depending on your test. These categories carry the most weight on each respective exam and lay the foundation for everything else. Then read our study tips guide for pacing, calculator policy, and test-day mechanics.
