Key examiner messages

Top priorities from the principal examiner before you revise

1

The June 2022 suite of papers for OCR Biology B represents a solid Level 4 difficulty.

2

The exam papers required students to move seamlessly between complex mathematical models, raw scientific data interpretation, and high-level medical case studies.

3

Rather than relying on simple recall, the papers targeted cognitive synthesis, especially in the Advance Notice section on exercise-induced acidosis and the statistical evaluation of agricultural trials.

Command word playbook

How to match each command word to the expected response style

ExplainFrequency: 18

Give reasons and link mechanism to outcome; each point needs a because/so chain.

DescribeFrequency: 12

State features in sequence or list observable properties — do not explain causes unless asked.

CalculateFrequency: 8

Show formula, substitution, and unit; method marks need visible working.

EvaluateFrequency: 7

Weigh arguments for and against with evidence; end with a supported judgement.

SuggestFrequency: 15

Apply knowledge to an unfamiliar context; concise, practical points score best.

StateFrequency: 10

Match the expected response style for “State” questions.
