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.
282 of 360 qualification marks reached this grade.
