How grade boundaries have moved
Lines show each boundary as a percentage of the qualification total. The gap from 2019 to 2022 covers the pandemic years, when normal summer examinations did not take place in 2020 or 2021. Summer 2022 used transitional grading arrangements.
Reading the pandemic-era data
There are no ordinary June 2020 or June 2021 boundaries because GCSE and A-level grades were awarded without the normal summer exam series. June 2022 was a transition year: Ofqual aimed for national outcomes midway between 2021 and 2019 as grading moved back towards pre-pandemic standards. The default calculator uses 2024–2026 for its recent range and keeps 2022 available for historical comparison.

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.
298 of 420 qualification marks reached this grade.
