Compare Two Note Taking Systems for a Long Non-Fiction Course

You are about to start a long course and taking notes the same way you always have, without checking if it actually works for something this long. This compares linear notes against a summary and cue system on time cost, revision ease, and whether it catches gaps early, then picks one.

You are choosing between two note taking systems for a long non-fiction course: linear notes taken as you go, and a Cornell-style system with a summary and cue column added after each session. Compare them on three points: how much extra time each takes per session, how easy each makes revision three months later, and which one better exposes gaps in your understanding while the course is still running. State clearly which system suits a long course better and why, in under 150 words.
