Heading, margin and three-level notes are habit; this confirms it and finds the few for whom it is not.
The heading and the margin are the same as last year, so this page is a check rather than a lesson — but there is one change: what you are expected to keep in the margin grows each year, and the standard for neatness is now whatever you managed at the END of last year, not the start.
Same page you have kept since Grade 3. Ten minutes to prove it.
