CIE 0610 Biology grade boundaries

Every grade threshold Cambridge published for 0610 Biology, covering March 2022 to June 2026: 14 sittings and 198 component thresholds, as the raw marks Cambridge prints and as percentages.

Read this before you read the numbers

These are past thresholds. They are not predictions.

Cambridge sets the threshold for a paper after that paper has been sat and marked, so the number moves every session with the difficulty of the paper and the performance of the whole cohort. Nothing on this page forecasts a future boundary, and no page on this site does. Use these to see the range a paper has sat in, not to decide what you will need next session.

Every number is copied from a named Cambridge document.

Nothing here is averaged, interpolated or estimated. The one figure calculated on this page is the percentage, which is the published mark divided by the maximum raw mark printed on the same row, rounded to the nearest whole number. The 14 source documents are listed at the foot of the page.

These are component thresholds, not overall grades.

Each row is one paper. Cambridge awards the overall grade from your total across the papers you sat, so clearing the A threshold on one component is not the same as an A for the syllabus.

Some papers cannot reach the top grades.

On a tiered syllabus a paper is set for one tier, and the tier limits the highest grade it can award. Cambridge publishes no threshold at all for those grades, so this table says "Not available on this tier" in that cell. It is not a blank we failed to fill and it is not a zero: the grade is not on offer for that paper.

Thresholds by component

Newest sitting first. 21 components, 14 sittings, grades A to G.

Where these numbers come from

Cambridge Assessment International Education, published grade thresholds. One document per sitting, named below exactly as Cambridge names it, so any figure in the tables above can be checked against the page it was copied from.

What to do with this

A boundary is only useful next to the paper it came from. These are the pages on this site for the same syllabus.
