Last-minute tips to ace the ACT or SAT: how to prepare the day before, the morning of, and during the test, plus test-day tactics to maximize your score.

After weeks or months of preparation, how you approach the final stretch matters. The goal now is to review strategically without exhausting yourself, so you walk in sharp, calm, and confident. This guide covers exactly how to handle the day before, the morning of, and the test itself.


The Day Before the Test

Most advice says don't study the day before, and that's mostly right, but a light review of the concepts you struggled with is worthwhile.

Keep it to 30–40 minutes, split across the sections that gave you trouble. If geometry tripped you up, revisit the questions you missed on practice tests so your weak spots are fresh. Don't overdo it, as cramming the night before does more harm than good.

Then step away. Do something you enjoy, take a walk to settle your nerves, and eat a healthy dinner, it affects your sleep, which is the single most important thing you can control tonight.

Get everything ready so you're not scrambling in the morning: your admission ticket, your fully charged device and power cord if you're testing digitally, and anything else your test center requires. Set your alarm with buffer time, and aim for 7–9 hours of sleep so you wake up genuinely rested.


The Morning Of the ACT or SAT

Give yourself plenty of time. Move through your normal morning routine so nothing feels rushed or unfamiliar, and plan your breakfast the day before. Make sure you eat something light and balanced rather than sugary, which can leave you sluggish in the back half of the test.

If you can, ask a parent or friend to drive you; staying clearheaded matters, and it's one less stressor to manage. Arrive early enough to find your room without pressure, and once you've checked in, take a mental note of the nearest restrooms and water fountains in case you need them.


During the Break

The test is intense, but you get a break partway through. Use it fully. Have a healthy, nutritious snack ready, such as an apple or a granola bar. Make sure you stay hydrated throughout. A quick trip to the restroom to freshen up will help you reset for the second half.


Test-Day Tactics

Beyond logistics, a few in-the-moment strategies can meaningfully affect your score:

Manage Your Time

Don't spend more than about a minute per question. If you get stuck, flag it, skip it, and come back at the end, leaving points on the table because you ran out of time on hard questions is one of the most avoidable mistakes.

Trust Your First Instinct

Your first answer is right more often than not. Only change it if you're genuinely certain your initial choice was wrong, second-guessing tends to cost more points than it saves.

Lean on the Habits You Built in Prep

The composure you want on test day comes from the routine you built beforehand, which is worth getting right well in advance (more on that below).


Build a Solid Practice Routine (Before You Get Here)

The best last-minute performance is really the product of good preparation. Two habits matter most in the weeks leading up to the test:

Start your prep by taking an official digital practice test to identify your strengths and weaknesses, then build your study plan around real data. There are lots of free SAT courses and tests available, so make sure to do them.

Rather than just checking your answers, keep an "error log" tracking exactly why you missed each question and which underlying concept you need to shore up. It's the single highest-leverage prep habit there is.

If you haven't chosen between the two tests yet, that decision shapes your whole prep, and our comparison of the ACT vs SAT walks through which is the better fit for you.


Being Ready for the Test

Acing the ACT or SAT isn't just about knowing the concepts, it's also about the techniques and mindset you bring on the day. Prepare well, rest well, and trust the work you've put in. You've got this, and we wish you the best on your exam.
