For photosynthesis, for instance, put it in the centre, then branch out to show: raw materials (carbon dioxide, water, light), products (glucose, oxygen), location (chloroplasts), limiting factors (temperature, light intensity, CO₂ concentration), and the two stages (light-dependent and light-independent reactions).

Divide each page into three sections: a narrow left-hand column for , a large right-hand column for detailed notes , and a bottom section for a summary . During revision, cover the right-hand column and use the cue column to test yourself. This method builds active recall directly into your note-taking process. biology o level 5090 notes better
