The high heritability of exam grades reflects many genetically influenced traits such as personality, behavior problems, and self-efficacy and not just intelligence.

The twins were assessed on a range of cognitive and non-cognitive measures, and the researchers had access to their GCSE (General Certificate of Secondary Education) scores.
