The self-marked option also calculates a cautious result after reducing entered marks by 10%. This is a planning allowance for uncertain marking.

4. Enter completed or estimated paper marks

Leave a paper empty when it is still to come. Enter 0 when it has been completed with a mark of zero.

What the answer means

The calculation adds all entered component marks and subtracts that total from the selected qualification boundary. Empty components supply the remaining available marks. The recent-range view repeats the calculation using June 2024, June 2025, June 2026.

If you choose Student / self-marked, the calculator also tests 90% of the marks you entered. That gives you a more cautious planning range when mark-scheme interpretation is uncertain; it isn't a measured error rate for you.
