Test scores aren't the whole picture, but they're one of the first things an admissions officer notices - and nobody perfect-scores by winging it. The good news: you can self-study to a strong score for free.
SAT or ACT?
- SAT: fully digital and adaptive, with harder questions but more time each - rewards critical thinking. A built-in Desmos calculator is allowed on all of Math.
- ACT: easier questions but very little time - rewards speed and fast reading. Since 2025 it's shorter, and Science is optional (it no longer counts toward your composite).
- Take one timed practice test of each before studying, then commit to whichever fits you. Rough targets: top schools ~1500+ SAT / ~34+ ACT; mid-high tier ~1430+ / ~30+. You do not need a perfect score to get in.
How to study (free first)
- Official practice tests are the best resource. Do timed sections, then review every miss and write down why you got it wrong.
- Khan Academy (free) is excellent; UWorld (paid) is a strong extra question bank.
- Popular books: College Panda (math), Erica Meltzer (English), and the SAT "Black Book" for strategy.
- Join a study Discord for free PDFs and motivation.
Skip the $1,000s prep classes. Self-study is usually cheaper and more effective; if you need help, a basic math/English tutor beats a big-name course. And you can test almost any month (Sept - Aug) - there's no secret "easy curve" month.
Don't sleep on the PSAT
A strong junior-year PSAT can make you a National Merit semifinalist/finalist - an award that brings real scholarship offers and perks. Plenty of students say it did more for them than the SAT itself.

Advice that keeps coming up on r/Sat and r/ACT:
- Save the official Bluebook practice tests. They're adaptive like the real digital SAT and the best predictor of your score, so take them timed, one at a time, and review every miss.
- Drill the free College Board Question Bank. Filter to hard questions to prepare for the tougher second module; the real test gets harder when you do well on the first.
- Learn Desmos. The built-in graphing calculator solves many math questions in seconds (systems of equations, intersections, quadratics), and there are endless Desmos trick threads.
- Plan for two or three attempts. Most colleges superscore, combining your best section scores across test dates, so one imperfect sitting isn't a disaster.
- On the ACT, pacing is everything. Practice with a timer from day one. If you always run out of time on a diagnostic, that's a sign the SAT fits you better.
