How we mark Biology

1. Identify command words

Describe vs explain vs evaluate. We know the difference and mark accordingly.

2. Check scientific terminology

Key terms must be present for marks. We identify exactly which terms were missing.

3. Level of response marking

6-mark questions marked holistically using level descriptors. Same as real AQA examiners.
