Study Techniques That Work
There are many study techniques and not every one suits everyone. But they share one thing: they work when the brain is active, not when you passively take in text. Here's a guide to the most effective ones so you can build your own system.
Active recall
The fundamental and most effective technique. Instead of re-reading, pull information from memory — with questions, flashcards, summaries in your own words. Every retrieval strengthens the memory and shows you what you don't yet know.
Spaced repetition
Review at growing intervals — a day, three days, a week. Your brain flags the material as important and stores it for good. Apps like Anki calculate the intervals automatically, but a calendar and discipline work too.
The Feynman technique
Explain a topic in simple words, as if to someone outside your field. Where you get stuck is a gap in understanding. It forces you to move from memorizing to real comprehension.
Interleaving
Mix topics and problem types within a session instead of long drilling of one thing. This trains you to recognize when to use which approach — exactly what an exam demands.
Audio learning: study by ear
A lesser-known but extremely practical technique: listen to material instead of reading when there's no room to read. Commutes, sport, and chores turn into revision, and combining heard and read text engages more senses, which helps memory.
You convert notes to audio with PDF2Audio — upload a PDF, pick a voice, and download an MP3 to listen offline. It's an ideal complement to active recall: during the day you read and test yourself, on the go you review the same by ear.
How to choose and combine
The best results come not from one technique but from combining them. A proven base: active recall + spaced repetition + listening on the go. Experiment and keep what genuinely holds your attention and delivers results.
In a nutshell
- Techniques where the brain is active — not passive — are the ones that work.
- Active recall and spaced repetition are the foundation.
- The Feynman technique reveals what you only memorize without understanding.
- Audio learning turns dead time into revision by ear.
- The best result comes from a combination, not a single method.

Which study technique is best?
Active recall combined with spaced repetition has the most evidence. The other techniques are great complements — pick based on what holds your attention.
Does learning by listening work?
Yes, especially as a complement to reading and recall. It lets you review when you can't read, and engaging hearing helps memory.
