Stop wasting hours re-reading notes. These 10 science-backed study tips will help you learn faster, remember longer, and ace your exams with less stress.
Backed by cognitive science research, these methods will transform the way you study.
Stop re-reading your notes over and over. Instead, close your book and test yourself on the material. Research from cognitive psychology consistently shows that retrieving information from memory — rather than passively reviewing it — creates stronger, longer-lasting neural connections. Quiz yourself with flashcards, write down everything you remember from a chapter, or explain concepts without looking at your notes.
Create flashcards for active recall →Cramming the night before might feel productive, but spaced repetition is far more effective for long-term retention. The spacing effect, first documented by Hermann Ebbinghaus, shows that we remember information better when we review it at increasing intervals. Instead of studying a topic for 4 hours straight, spread those sessions across multiple days. Apps like Stacked use spaced repetition algorithms to schedule your reviews at the optimal time.
Try spaced repetition in Stacked →Your brain was not designed for marathon study sessions. The Pomodoro Technique breaks study time into focused 25-minute intervals with 5-minute breaks. After four rounds, take a longer 15 to 30 minute break. This method combats mental fatigue, maintains concentration, and gives you a clear structure so you actually start studying instead of procrastinating. Track your Pomodoros to see your productivity add up over time.
Use the free Pomodoro Timer →Flashcards are one of the most effective study tools because they naturally incorporate active recall. Every time you flip a card, you are forced to retrieve the answer from memory before checking. Digital flashcard apps take this further by tracking which cards you struggle with and showing them more frequently. With Stacked, you can generate flashcards from your notes, photos, or PDFs using AI — no manual typing required.
Build a flashcard deck now →The Feynman Technique, named after Nobel Prize-winning physicist Richard Feynman, is simple: if you cannot explain a concept in plain language, you do not truly understand it. After studying a topic, try explaining it out loud as if you are teaching a beginner. When you get stuck or use vague language, go back and study that specific gap. This method exposes weak spots in your understanding that passive reading never would.

Research shows it takes an average of 23 minutes to fully regain focus after a distraction. Put your phone in another room (or use a focus mode), close unnecessary browser tabs, and find a quiet environment. If you need background sound, try white noise or ambient music without lyrics.
Sleep is not a luxury — it is when your brain consolidates memories and moves information from short-term to long-term storage. Studies show that students who sleep 7 to 9 hours perform significantly better on tests than those who pull all-nighters. Prioritize sleep during exam season, even if it means studying a little less. A well-rested brain retrieves information faster and thinks more clearly.
Even 20 minutes of moderate exercise — a brisk walk, a jog, or a quick workout — can boost focus, mood, and memory. Physical activity increases blood flow to the brain and stimulates the release of BDNF (brain-derived neurotrophic factor), a protein that supports learning and memory formation. Schedule a short exercise session before your most important study blocks for maximum cognitive performance.
Engaging more than one sense while studying creates multiple pathways to the same memory, making it easier to recall later. Read your notes out loud (sight + sound), draw diagrams (sight + touch), or walk around while reviewing flashcards (movement + sight). Studies in multimodal learning show that combining sensory inputs leads to deeper encoding and stronger recall than using any single method alone.
Your brain processes and consolidates information during sleep, especially during deep sleep and REM cycles. Doing a quick review session of your most important material right before bed gives your brain fresh information to work with overnight. Keep it light — 10 to 15 minutes of flashcard review is ideal. When you wake up, you will often find that the material feels more solid than it did the night before.
