| Course | Code | Written assessment |
|---|---|---|
| Gateway Biology A | J247 | Two papers at the chosen tier, 1 hour 45 minutes each. |
| Twenty First Century Biology B | J257 | Breadth and Depth papers, 1 hour 45 minutes each. |
Both courses have 90 marks per paper, with each paper worth 50%. Their organisation differs, so use the correct course materials. In a lesson on movement across membranes, for example, a tutor might ask your child to draw particles, describe what changes and explain why. Only then would they turn that understanding into a concise written answer.
Explain a diagram
Label a structure and connect each part to its function. Practise describing what the diagram shows without relying on its labels alone.
Read the evidence
Choose figures from a graph to support a comparison. Notice whether the question asks for a description or an explanation.
Think through an investigation
Identify what changes, what is measured and what needs controlling. Explain how a proposed improvement would help.
Do not assume so. The listings identify OCR experience, but you should confirm J247 or J257 and your child’s tier with the individual tutor before arranging lessons.
No. These are separate GCSE Biology qualifications. If your child studies Combined Science, give the tutor that course title and code so the content and paper practice match.
Arrange a free 15-minute introduction to discuss your child’s confidence, current topics and any marked work. Ask how the tutor checks understanding during a lesson.
