One of the most common IB fears is this: “If too many students take my subject, does that make it harder to get a 7?”
It’s an understandable concern. When subjects like English A, Biology, or Business Management have massive global cohorts, it can feel like competition is stacked against you. But this fear often leads students to make poor decisions — either avoiding subjects they enjoy or blaming results on enrolment rather than preparation.
This article explains whether subject popularity actually affects your chance of scoring a 7, and what truly separates top-scoring IB students from everyone else.

How the IB Awards a 7
IB grading is criterion-based, not relative.
This means:
- You are not competing directly against other students
- There is no fixed number of 7s per subject
- Meeting the highest criteria earns the highest grade
If your work meets the descriptors for a 7, you receive a 7 — regardless of how many students took the subject alongside you.
Popularity does not limit how many students can score highly.
Why Popular Subjects Feel More Competitive
Although grading is not relative, popular subjects feel more competitive for good reasons.
In high-enrolment subjects:
- Examiners see thousands of similar answers
- Generic responses are filtered out quickly
- Weak structure stands out immediately
