Are these the exact grade boundaries?

No. Real boundaries are released by each board every summer and shift with how hard the papers were. This checker uses representative recent percentages so you get a realistic estimate, not an official result.

Why do boundaries change every year?

Boards set boundaries after marking so that a given grade reflects the same standard despite differences in paper difficulty. A harder paper lowers the boundary, an easier one raises it, which is why fixed percentages are only a guide.

How is my grade worked out here?

The tool turns your raw mark into a percentage of the total, then checks it against the board's typical boundary percentages for A* down to E. The highest band your percentage clears becomes your estimated grade.

Why do A-Levels use uniform marks?

Linear A-Levels combine several papers, and boards often convert raw marks to a uniform mark scale before applying boundaries. For a quick estimate you can enter your combined raw total against the combined maximum and read the band.

Can I trust this for results day predictions?

Use it for a rough self-check only. Until your board publishes the actual boundaries for your series, no tool can tell you the precise grade, especially near a boundary where a mark or two decides the outcome.

Estimating your A-Level grade from a raw mark

After a mock or a real paper you often know your raw mark but not the grade it earns, because that depends on grade boundaries the exam board sets later. This checker gives you a realistic estimate by comparing your percentage against representative recent boundaries for AQA, Edexcel and OCR.

How it works

The tool first turns your raw mark into a percentage of the total marks available. It then compares that percentage against a table of typical boundary percentages for your chosen board — for example, an A* near 80 percent, an A near 70 percent, a B near 60 percent, and so on down to E. The highest band your percentage clears is your estimated grade. The tool also reports how many extra marks would be needed to cross into the next grade up, which is useful for judging how close you are to a boundary.

Important caveats

Grade boundaries are not fixed. Each board publishes them every summer and adjusts them so a grade reflects a consistent standard despite paper difficulty. A harder paper pushes boundaries down and an easier paper pushes them up, sometimes by several marks. Treat the result here as a guide, especially when your mark sits within a few percent of a boundary, where the real outcome can swing either way. Once your board releases the official boundaries for your series, use those for the definitive answer.
