A plateau usually means the practice isn't targeted. If scores have stalled, stop adding papers and start diagnosing exactly where the marks are being lost — the same gaps are probably reappearing each time.
Flat scores are frustrating, but they're information. One possible cause is repeating whole papers without fixing the specific weaknesses they reveal, so the same marks can be lost each time.
Break the pattern: take the last two or three papers and group every mistake by topic, looking for one or two skills that may be contributing disproportionately to the lost marks. Check too whether the difficulty has changed, and whether timing or careless slips are holding the score down even when the knowledge is there. Then fix the biggest issue properly before the next paper.
Keep the tone calm and practical — pressure tends to make a plateau worse, not better.
What to do: pause the paper treadmill, compare the last few papers, group recurring mistakes, fix the biggest one, and check timing and slips.
Smart Papers surface those recurring gaps automatically and point to the free lessons that close them — turning a plateau into a plan.
