Question 1

What are OCR A-Level Computer Science grade boundaries?

Accepted Answer

Grade boundaries are the minimum raw marks you need for each letter grade in OCR A-Level Computer Science (specification H446 Overall (all options)). OCR sets them once marking is complete for the whole cohort: senior examiners review evidence from the exam series, compare performance with previous years, and recommend where each boundary should sit. They're then normally published on A-Level results day, alongside the grades themselves.

The boundaries move a little from year to year, because every paper is a slightly different test. If a paper turns out more difficult than usual, the boundaries come down. If it's more accessible, they nudge up. The aim is that a grade represents the same standard whichever year you happened to sit the exam, even though the raw mark needed will vary between series.

Question 2

Why do the OCR A-Level Computer Science boundaries change every year?

Accepted Answer

Because every paper is a slightly different test. Once marking is complete, senior examiners review evidence from the exam series, compare performance with previous years, and recommend where the boundaries should sit for each grade. If the paper turned out more difficult than usual, the boundaries come down. If it was more accessible, they nudge up.

The point of that adjustment is fairness across cohorts: a grade should mean the same thing whichever year you sat it. That's also why comparing raw marks across years can be misleading, since the same total might have been a C in one series and a B in another.

Question 3

When are the OCR A-Level Computer Science grade boundaries published?

Accepted Answer

OCR normally publishes A-Level grade boundaries at 8am on A-Level results day, alongside the grades themselves. They land on OCR's grade boundaries page and cover every A-Level specification in a single document.

We update this page the same morning with the new row, so you can look up your total against the fresh boundaries and see what grade it would have earned.

Question 4

What mark do I need for an A* in OCR A-Level Computer Science?

Accepted Answer

It depends on the year, because OCR sets the boundaries once the cohort has been marked. In recent series, the A* boundary has sat between 264 and 292 marks out of 350 (roughly 75 to 83 percent). The exact figures per series are in the table above.

A sensible working target through your revision is to aim comfortably above the highest recent boundary in past-paper practice, which gives you some headroom for the exam room. Whether that translates to an A* in your specific series will depend on how the cohort performs overall and how the papers land.

Question 5

How should I use these boundaries when I'm revising?

Accepted Answer

There are two ways worth building into your routine.

**Score your past papers realistically.** Sit a paper timed, mark it against the official mark scheme, and if you've completed a full set of papers, compare your total against that year's overall boundary in the table above. That's the grade it would have earned in that series, and exactly how many marks you were short of the next one.

**Set your target using an average.** A practical target is to aim around the average of the last few years' boundaries for the grade you're going for. That's more realistic than aiming at the highest recent year, in case the next paper is more difficult, and more ambitious than aiming at the lowest, in case it's more accessible.

Our [A-Level Computer Science (OCR) past papers](https://cognito.org/courses/alevel/computer-science/ocr/past-papers/by-year) collection has every year's paper and mark scheme in one place.

Question 6

Does Cognito have OCR A-Level Computer Science past papers?

Accepted Answer

Yes! Our [A-Level Computer Science (OCR) past papers](https://cognito.org/courses/alevel/computer-science/ocr/past-papers/by-year) collection is free and has every published paper and mark scheme in one place, so you can sit them under timed conditions and mark against the official scheme.

For past-paper revision, we'd suggest starting with topic-by-topic questions in the run-up to your mocks, then saving two or three full timed papers for the last few weeks before your exam.
