Study Tips
- 1
Do practice problems every day — math is learned by doing, not by re-reading notes.
- 2
Keep an error log: write down every mistake, why it happened, and redo the problem a week later.
- 3
Show every step of your working — most exams award method marks even when the final answer is wrong.
- 4
Take full-length, timed practice tests under real conditions — stamina and pacing matter as much as content.
- 5
Review every wrong answer until you can explain why the right answer is right and yours was wrong, then log the mistake.
- 6
Learn the recurring question types — the SAT and ACT reuse the same patterns every administration, so familiarity is free points.
- 7
Master pacing: know your per-question time budget and practice skip-and-return so you never leave easy points behind.
- 8
Use aggressive elimination — rule out wrong choices on every question before you commit to an answer.
- 9
Attack your weakest section with focused drills between full tests; a few points per section compound fast into a big composite gain.
- 10
Simulate test day exactly — same start time, same breaks, no phone — so the real thing feels routine.
