You’ve studied for weeks, revised your notes, and taken countless practice tests. But as test day approaches, even the most prepared students can make critical mistakes that impact their final score. At 700 Plus Club, we’ve worked with hundreds of students and identified the most common mistakes and pitfalls that occur right before test day – and how you can avoid them.
Whether you’re sitting the GMAT, GRE, SAT, or any other high-stakes exam, here are the top mistakes to steer clear of in the final hours and days.
1. Cramming the Night Before
It’s tempting to stay up late and squeeze in every last bit of information. But cramming rarely helps – and more often than not, it backfires. Your brain needs time to consolidate information and function at its best, which won’t happen if you’re mentally exhausted.
What to do instead:
Use the evening before to review lightly – go over key concepts or flashcards, but avoid tackling anything new. Most importantly, aim for 7–9 hours of quality sleep.
2. Neglecting Physical and Mental Wellbeing
Students often focus so much on test content that they forget the basics: hydration, nutrition, exercise, and mental rest. Showing up tired, hungry, or anxious can affect your performance as much as not knowing the material.
What to do instead:
- Eat a balanced meal the night before and a light, protein-rich breakfast on test day.
- Stay hydrated but don’t overdo caffeine.
- If you feel nervous, try breathing exercises or meditation the evening before.
At 700 Plus, we encourage students to treat test day like an athletic performance – mind and body both need to be in peak condition.
3. Not Knowing the Test Logistics
One of the most avoidable mistakes is arriving late, getting lost, or forgetting what you need to bring. This adds unnecessary stress and can even result in being turned away.
What to do instead:
- Double-check your test location, time, and ID requirements a few days before.
- Pack everything (ID, confirmation email, snacks, water, pencils) the night before.
- Aim to arrive 30–45 minutes early.
If you’re taking the test online, test your equipment in advance. Ensure your internet connection, webcam, and microphone are all functioning properly, and that your room meets the testing criteria.
4. Second-Guessing Your Preparation
Imposter syndrome is real. Even students who’ve consistently scored well on practice tests can spiral into self-doubt the night before the exam.
What to do instead:
Remind yourself that you’ve done the work. Try to avoid comparing your preparation to others – everyone learns differently. Trust your strategy, stick to your pacing plan, and don’t let nerves derail your focus.
Pro tip from our tutors: The day before, write down a few key affirmations or reminders (e.g. “I’ve prepared well. I know my strengths. I can handle this.”) and read them aloud in the morning.
5. Doing Full-Length Practice Tests Too Late
Some students try to squeeze in one last full-length test just a day or two before the real one. While this may seem like a good idea, it can lead to mental fatigue or even shake your confidence if the result isn’t as strong as expected.
What to do instead:
If you want to stay sharp, do a sectional review or tackle a few targeted questions in weak areas. Save full-length practice exams for earlier in your prep – ideally at least 3–5 days before test day.
6. Ignoring the Importance of a Routine
Test day is not the time to try new foods, change your sleep schedule, or test out new supplements. These small changes can throw off your body or cause unwanted surprises.
What to do instead:
Stick to what’s familiar. Eat the same breakfast you’ve had on successful practice test days. Follow a routine that feels comfortable and calming. Repetition reduces anxiety – your brain likes knowing what to expect.
Set Yourself Up for Success with the Right Mindset
The final 24–48 hours before your exam should be about staying calm, focused, and confident – not scrambling to learn something new or questioning your abilities. At 700 Plus Club, we believe peak performance comes from a mix of solid preparation and smart mental habits.
By avoiding these common mistakes and sticking to a well-planned routine, you’ll give yourself the best possible chance of hitting your target score – and beyond.
