Night Before ACT: What Students Should Do

The night before ACT can be just as important as the weeks of preparation leading up to it. Your goal is to maximize focus, reduce anxiety, and enter the test day confident and prepared. Here’s how to make the most of the evening before the big day:

1. Avoid Last-Minute Cramming

Research shows that trying to learn new concepts the night before ACT often increases stress and reduces retention. Instead, focus on reviewing key formulas, vocabulary, or problem types you’ve already practiced. Use resources like Top Marks Prep, which offers adaptive review to pinpoint your strengths and areas that need light reinforcement.

2. Organize Your Materials

Lay out everything you’ll need for test day the night before so you're not searching for anything the morning of.

• Admission ticket and a valid photo ID

• Two or three No. 2 pencils, a good eraser, and a permitted calculator (check ACT's current approved calculator list — most graphing calculators are fine, but phones and smartwatches are not, even for timekeeping)

• Extra batteries for your calculator

• A simple analog watch if you plan to track time yourself. Smartwatches and phones are not allowed on your desk

• Layered clothing. Testing rooms are notoriously either freezing or overheated, and you can't control the thermostat.

• Snacks and water for the break. Something with slow-release energy, like a granola bar, banana, or trail mix, is a great option rather than sugar that may cause you to spike and crash.

Organizing tonight means your morning is simply execution, not a scavenger hunt. 

3. Plan Your Morning Routine

Set an alarm with enough time to eat a healthy breakfast, get ready, and arrive at the test center early. Avoid any late-night habits that disrupt sleep, such as scrolling on your phone or pulling an all-nighter.

4. Relax and De-Stress

Practice deep breathing, light stretching, or even a brief walk. Staying calm the night before ACT helps lower cortisol levels, which improves focus and memory recall. Remember, confidence comes from preparation, not perfection.

5. Set a Real Bedtime, Not Just "Get Good Sleep"

Aim to be in bed with lights off by 10 p.m., especially if your test starts at 8 a.m. Working backward from a 7–8 hour sleep goal, most students need to be asleep by 10–10:30 p.m. to wake up naturally instead of groggy. Sleep consolidates memory, so this isn't just about feeling rested — it directly affects recall on the Reading and English sections tomorrow.

6. Eat a Real Breakfast

Skip the sugary cereal or nothing-at-all approach. Aim for protein plus complex carbs — eggs and toast, Greek yogurt with granola, or oatmeal with peanut butter — about an hour before you leave. This keeps blood sugar steady through a 2+ hour test instead of causing a crash by the Math section.

If You Want Extra Review Tonight

If you want a low-stress way to review tonight, adaptive tools like Top Marks Prep let you do short, targeted practice instead of guessing what to look at. This is useful if you have 20–30 minutes and want to feel more prepared without opening a full practice test.

FAQs

Q: Should I do any practice tests the night before ACT?
A: No. The night before, focus on light review and confidence-building exercises rather than full tests. 

Q: Is it okay to skip breakfast on test day?
A: Absolutely not. Eating a balanced breakfast stabilizes energy levels and helps concentration. Bring snacks for a mid-test boost if needed.

Q: How can I reduce anxiety the night before ACT?
A: Relaxation techniques (deep breathing, a short walk), reviewing only familiar material, and having your materials ready in advance all reduce the last-minute stress that hurts performance most.

Q: Can I review new topics the night before?
A: Avoid learning anything new. Focus on reviewing material you are already familiar with to prevent stress and cognitive overload.
