A lot of students “study” by repeatedly looking at information and hoping it stays in their brain.

But it doesn’t work like that. Re-reading, highlighting, copying notes, watching lectures, following along – all of it can feel productive while leaving very little in long-term memory.

The test of learning is simple: can you reproduce it from memory and use it to solve problems? If not, you have not learned it yet.

The brain does not care how many times you looked a piece of information. It cares how many times you pulled it back from memory under increasingly difficult conditions.
