Study Techniques That Actually Work (and the Ones That Don't)

Most study advice is folklore. Highlighting, rereading, and "just put in the hours" feel like studying, which is exactly why they're so popular — and why they work so poorly. When researchers actually test methods against each other, a small set wins every time, and they're rarely the ones students reach for first.

Here are the techniques that hold up, worst-to-best of the popular ones, then the routine that ties the good ones together.

The ones to drop

• Rereading builds familiarity, not memory. It's the most common method and one of the weakest.
• Highlighting marks text for a reread that won't help. It feels productive and changes almost nothing.
• Massed practice (long single-topic cram sessions) fades fast — you're studying the same state of mind, not building durable recall.

None of these are harmful; they're just a poor use of the hours you have.

The ones that work

1. Test yourself (active recall). Close the book and produce the answer from memory. Retrieving a fact strengthens it far more than seeing it again. This is the single biggest lever — start here. → Active recall

2. Space it out (spaced repetition). Review material across days, just before you'd forget it, instead of all at once. You spend less total time and remember much more. → Spaced repetition

3. Explain it simply (the Feynman technique). Teach a concept in plain words. Where you stumble is exactly the gap to fix — this turns "I sort of get it" into real understanding. → The Feynman technique

4. Take notes that force thinking. Notes you have to think to write — in your own words, as questions — are notes you can study from. → How to take notes

The routine that combines them

You don't need all four as separate rituals. They stack into one loop:

1. Read or attend the lesson and take notes as questions.
2. Turn those into recall practice — test yourself instead of rereading.
3. For anything you keep missing, explain it out loud until it's clear.
4. Revisit it on a spaced schedule so it sticks.

That's the entire system that beats cramming, and it's what a good exam study plan is built from.

Cut the friction

The reason people fall back on rereading is that the good methods take setup — writing questions, building flashcards, tracking what's due. Sinau removes that step: give it your notes, a photo, or a PDF, and it produces the summary, quiz, and flashcards, then runs the spaced-repetition schedule for you. The techniques do the work; you just have to show up and recall.
