Find My Technique →Memory · Long-term retention
Review material at increasing intervals so your brain never forgets it.
What it is
Spaced repetition is based on the forgetting curve — the idea that we naturally forget information over time unless we review it. Instead of reviewing everything every day, spaced repetition has you revisit material just before you're about to forget it, which strengthens the memory each time. The gaps between reviews get longer as you get better at recalling something.

How to do it
Pro tip: The free app Anki does all the scheduling automatically. You just answer whether you got it right or wrong, and it handles the rest.
Memory · Self-testing
Stop re-reading. Start retrieving. Your brain learns by pulling information out, not putting it in.
What it is
Active recall means testing yourself on material instead of passively reading it. Re-reading creates an illusion of knowing — things feel familiar, but familiarity isn't the same as memory. Retrieving information from scratch is what actually builds strong, lasting memory. Every time you successfully recall something, the neural pathway for that memory gets stronger.

How to do it
Pro tip: The gaps feel uncomfortable — that's a good sign. The difficulty of retrieval is what makes the memory stick. If it felt easy, you probably already knew it.
Note-Taking · Organization
A note-taking system that turns your notes into a built-in study tool.
What it is
Developed at Cornell University, this system divides your note page into three sections: a narrow left column for keywords and questions, a wide right column for your actual notes, and a summary section at the bottom. The magic is what happens after class — you use the left column to quiz yourself on the right, turning your notes into an instant self-test tool.

How to do it
Pro tip: The summary is the most important part. Forcing yourself to condense an entire page into a few sentences is what moves information from short-term to long-term memory.
Focus · Time management
25 minutes of focus. 5 minutes of rest. Repeat. Simple — and it actually works.
What it is
Created by Francesco Cirillo in the 1980s using a tomato-shaped kitchen timer (pomodoro is Italian for tomato), this technique breaks work into 25-minute focused intervals separated by short breaks. The structure works because it makes starting easier — 25 minutes feels manageable — and the built-in breaks prevent mental fatigue. It also stops the guilt spiral of studying with a distracted mind for hours.

Deep Understanding · Teaching
If you can't explain it simply, you don't really understand it yet.
What it is
Named after Nobel-winning physicist Richard Feynman, this technique is built on one idea: real understanding means being able to explain something simply. You study a concept, then explain it out loud as if teaching a complete beginner — no jargon, no hiding behind big words. The moment you stumble or go blank is the exact moment you've found a gap in your understanding. You go back, fill it, and explain again.

How to do it
Pro tip: You don't need an actual person to teach. Explaining to your mirror, a stuffed animal, or even out loud to yourself works just as well. The act of speaking forces your brain to organize what it knows.
Understanding · Visual thinking
See the whole picture at once — and how every piece connects.
What it is
A mind map is a visual diagram that starts with one central idea and branches outward into subtopics, details, and connections — like a tree. Unlike linear notes, mind maps show how concepts relate to each other, which is how your brain actually stores information. They're especially powerful for subjects with lots of interconnected ideas and for people who think visually.

How to do it
Pro tip: Paper works better than apps for most people — the physical act of drawing slows you down enough to actually process the information. Try a large sheet of blank paper and colored pens.
Reading · Comprehension
A structured way to actually read and retain a textbook chapter — not just skim it.
What it is
SQ3R stands for Survey, Question, Read, Recite, Review. It's a reading comprehension strategy that turns passive reading into an active, structured process. Instead of reading a chapter from start to finish and hoping it sticks, SQ3R gives your brain a framework before you even start reading — which dramatically improves how much you retain.
Best for
How to do it
Pro tip: The Survey step alone will change how much you retain. Most people skip it — don't. Knowing the structure of a chapter before you read it gives your brain a mental "filing system" for the information.
Memory · Study strategy
Mix up your subjects. It's harder — and that's exactly why it works.
What it is
Most people study one subject for a long block of time — all math, then all history, then all biology. This is called blocking, and it feels productive but leads to poor long-term retention. Interleaving means alternating between different topics or problem types during the same study session. It feels harder and messier, but research consistently shows it leads to stronger memory and better ability to apply knowledge in new situations.
Best for
How to do it
Pro tip: Interleaving works especially well for math. Instead of doing 20 algebra problems in a row, mix in 5 geometry, 5 algebra, 5 statistics. You'll score better on exams that mix problem types — which most exams do.
Understanding · Critical thinking
Ask "why?" and "how?" until you actually understand — not just memorize.
What it is
Elaborative interrogation means generating explanations for facts — asking yourself "why is this true?" and "how does this work?" instead of just accepting information at face value. It connects new knowledge to things you already know, which makes it far stickier. This is especially powerful for subjects that require understanding over memorization.
Best for
How to do it
Pro tip: This works incredibly well alongside your regular notes. For every major fact you write down, add a "why?" question next to it. Come back and answer it without looking.
Memory · Flashcards
A physical flashcard system that guarantees you spend your time where it matters most.
What it is
The Leitner System is a physical version of spaced repetition using flashcards sorted into boxes. Cards you struggle with get reviewed more often. Cards you know well get reviewed less. Over time, your hard cards work their way into easier boxes, and you can see your progress literally in front of you. It's simple, tactile, and requires no apps.

How to do it
Pro tip: The moment a card goes back to Box 1 can feel frustrating — but that's the system working exactly as it should. It found a gap before your exam did.
