Most students don’t know why they lose marks.

Carry the proof
A progress report built from work you actually did — shareable with a parent, honest about what it can and can't show.

For parents
Finally, an honest answer to “is it working?”
A parent view shows readiness, consistency and exactly which gaps are being worked on — in plain language, with no exam jargon. It will never show you a predicted rank, because nobody can honestly produce one from practice data.
