📓 How to Take Notes That Actually Help You Revise

There are two kinds of notes: notes that look beautiful, and notes that raise marks. Occasionally they overlap, but the decoration is not what does the work. Good notes have one job — to make future revision fast and testable. Here is how the best students take them.

The golden rule: compress, don't copy

Copying the board or textbook word-for-word is transcription, not learning. The value of note-taking comes from compression — forcing the material through your brain and out in fewer, your-own words. A page of textbook should become a third of a page of notes. If your notes are as long as the source, they are photocopies with extra effort.

The Cornell method (the classic that works)

• ▸Divide the page: a narrow cue column on the left, wide notes area on the right, summary strip at the bottom.
• ▸During class: capture ideas in the right column — short phrases, abbreviations, diagrams.
• ▸Same evening: write questions in the left cue column ('Define osmosis?', 'Formula for CI?') opposite each chunk.
• ▸To revise: cover the right side, answer the cue questions from memory. Your notes just became a self-test.

Other formats worth knowing

• ▸Mind maps — best for connected topics (history chapters, biology systems): central idea, branches, single keywords per branch.
• ▸Formula sheets — one page per subject of every formula, built as you go; gold in the final week.
• ▸Error log — a notebook purely of your past mistakes and their corrections; the highest-scoring notebook you will ever own.

Small habits, big difference

• ▸Leave white space — cramped pages cannot absorb later additions.
• ▸Date and title every page; future-you searches by chapter.
• ▸Rewrite nothing 'to make it neat' — spend that hour testing yourself on it instead.
