OCR GCSE Combined Science A: Gateway grade calculator

Calculate the double grade needed across the six OCR Gateway Combined Science papers.

Marks-needed calculator

Foundation tier

360 marks total

Simple mode uses the spread of the June 2023–2025 boundaries. In-depth mode adds an exact-year option and fuller grade analysis.

1. Choose a boundary set
2. Choose the target grade
3. Who marked the papers?

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 the paper has been completed with a mark of zero.

Boundary trends

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 with grading set between 2019 and pre-pandemic standards. The default calculator therefore uses 2023–2025 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 2023, June 2024 and June 2025.

Self-marked work receives an additional cautious calculation using 90% of the entered marks. It gives a wider planning range where mark-scheme interpretation may be uncertain. It does not alter the marks entered or claim a measured error rate for any individual student.
