The best study techniques, ranked by evidence

Highlighting and rereading feel productive but barely work. Here's what cognitive science says actually builds durable memory — and how to combine the winners.

The evidence hierarchy

Practice testing (active recall) and distributed practice (spaced repetition) sit at the top of the evidence pyramid, with interleaving and elaborative interrogation close behind. Rereading, highlighting, and summarizing rank near the bottom.

How to actually use them

Turn notes into questions, test yourself before you feel ready, space reviews on an expanding schedule, mix problem types instead of blocking them, and explain concepts in your own words — the Feynman technique.

Technique + time

Techniques need protected time to live in. Pair them with Pomodoro sessions and the 2-hour study method inside FocusArx, where flashcards and session tracking make recall practice a daily habit.
