How to Study the Night Before a Test (Emergency Cram Guide)

TL;DR

If you MUST cram: focus on the most important 20% of material, use active recall (not passive reading), study in 25-minute blocks with breaks, make a one-page cheat sheet, and get at least 5 hours of sleep. A rested brain with 70% of the material beats an exhausted brain with 90%.

Let's Be Real

You shouldn't be cramming. Distributed studying over multiple days is scientifically proven to be more effective. But you already know that, and you're reading this at 9 PM with a test at 8 AM. So let's make the most of what you've got.

The Emergency Cram Protocol

Step 1: Triage (15 minutes)

You can't learn everything. Decide what to focus on:

• Review the study guide or syllabus for the test
• Identify the topics worth the most points
• Rank topics by difficulty for you (hardest = most study time)
• Accept that you'll skip some material — focus on the highest-value content

Step 2: Active Study (2-3 hours, with breaks)

Use the Pomodoro method: 25 minutes studying, 5 minutes break.

During study blocks:

• DON'T just re-read notes. It feels productive but doesn't work.
• DO quiz yourself. Close your notes and try to remember key concepts.
• DO work practice problems. For math/science, solving problems is studying.
• DO create a one-page cheat sheet. Even if you can't use it during the test, the act of condensing information is incredibly effective.

Step 3: Focus on Key Terms and Concepts

• Make quick flashcards (physical or digital) for key vocabulary
• Review them twice: once now, once right before bed
• Focus on UNDERSTANDING the big concepts rather than memorizing details

Step 4: Get at Least 5 Hours of Sleep

This is non-negotiable. Your brain consolidates learning during sleep. An all-nighter might add 3 more hours of study, but it takes away:

• Memory consolidation
• Focus and concentration
• Reading comprehension
• Decision-making ability

Set an alarm and GO TO SLEEP.

Step 5: Morning Review (15-20 minutes)

Wake up, eat breakfast, and do a quick review:

• Scan your cheat sheet
• Review the flashcards you made
• Focus on anything you couldn't remember last night

What to Cram vs. What to Skip

CRAM These:

• Key vocabulary and definitions
• Formulas and how to use them
• Major concepts and their significance
• Material your professor explicitly said would be on the test

SKIP These:

• Minor details you'll never remember anyway
• Topics worth few points on the exam
• Material you already know decently well
• Supplementary readings not covered in lecture

During the Test

• Brain dump: Write key formulas and terms on scrap paper immediately
• Easy questions first: Build confidence and secure easy points
• Guess strategically: Eliminate wrong answers, then guess
• Don't leave blanks: Any answer is better than no answer

A Note for Next Time

Cramming works just well enough to feel justified, which is why students keep doing it. But the material doesn't stick, and your grade is lower than it would be with proper studying.

Next time, try studying for 30 minutes a day starting a week before the test. It's less total time than cramming AND you'll score higher. Win-win.

Cramming isn't ideal, but it's better than not studying at all. Follow this protocol, get some sleep, and do your best. Tomorrow night, start studying for the NEXT test early. Deal? 🌙
