Summarizing
Summarizing is the study skill of condensing material into its key points in your own words. It forces you to decide what actually matters and to check that you understood it, because you cannot restate an idea clearly until you have grasped it.
When you summarize, you do not just copy. You sort the important from the filler, link ideas together, and rebuild them in your own wording. That act of deciding and rephrasing is what moves the material into long-term memory, far more than rereading or highlighting does.
The common mistake is summarizing too early or too long. A summary that is almost as long as the original means you skipped the hard part, which is choosing what to cut. If you cannot shrink a chapter into a few clear lines, that is a signal you have not understood it yet, not a reason to keep everything.
After a biology lecture on cell respiration, Mara closes her notes and writes four lines from memory: glycolysis splits glucose, the Krebs cycle releases carbon, the electron chain makes most of the ATP, oxygen is the final acceptor. The two steps she could not write became her revision targets.
