Feynman Technique
Explain a topic out loud as if teaching a ten-year-old. The places you stumble are what you do not yet understand.
Example
You think you understand photosynthesis. Try explaining it to your younger cousin, in plain words, without using the word 'photosynthesis'. The bit where you reach for jargon ('chlorophyll', 'glucose') is exactly where the gap is.
How it fits in
Reading something and recognising the words is not the same as understanding it. The Feynman Technique forces you out of recognition and into explanation. The places you reach for jargon are the places your understanding is thin. Going back and filling those gaps is much faster than re-reading the whole topic.

The way of thinking you reach for first, plus a second one you can practise for when the first one stalls.
Test yourself instead of re-reading. Pulling information out of your head is what builds memory, not putting it back in.
