Pick a picture, plan it in five boxes, then write. The clock and the word count are handled for you — you just write the story.

Twenty-four picture sets, in the format her paper uses: three scenes and a theme. Read all three before planning — the marks are in how they connect.
No clock is for an ordinary day — take as long as you like. Exam starts the real timer, for when you want to practise like the actual paper.
Three or four words per box. Not sentences — a plan she has to read twice is too long.
Four paragraphs: scene, problem, action, ending. The plan stays visible above the box.
One pass per point, in order. A single vague read-through catches almost nothing.
Found automatically. Each one is a place a stronger word usually fits — not an error, and not something to replace without reading the sentence.
She marks it against the band table before anyone else does. Self-diagnosis is the skill.
Every composition, dated and marked, kept in order. Progress at this age is invisible week to week and obvious across ten weeks — this is the only place that shows it.
