Self-explanation
Self-explanation is a study habit where you stop and explain to yourself why a step, fact, or answer is actually true, out loud or on paper. It forces you to fill in the reasoning instead of just nodding along, which is where most fake understanding hides.
The trick is simple. Every few lines, you pause and ask yourself why this is true or how this step follows from the last one, then you answer in your own words. When you can't, you just found a hole you didn't know was there. That gap is the whole point, because skimming feels like learning but it skips the reasoning.
Most people skip this because explaining out loud feels slow and a bit silly. It is slower, but that slowness is the work. The common mistake is summarizing what the page said instead of explaining why it's true. If you only repeat the words, you never test whether you actually get it.
Sarah is studying for biology and reads that the heart's left ventricle has a thicker wall than the right. Instead of moving on, she stops and says out loud why: the left side pumps blood to the whole body, the right side only to the lungs, so it needs more muscle. The moment she had to give a reason, the fact stuck.
