A-Level Biology OCR A H420

Specification

Here is a summary of the OCR A Level Biology A (H420) Specification, Version 3.4 (June 2025), for first assessment in summer 2025.

1. Introduction & Overview

  • The specification is designed for flexible teaching, divided into six modules.
  • Module 1 focuses on practical skills, assessed through written exams and a Practical Endorsement (non-exam assessment).
  • Modules 2–6 cover core biological content, integrating theory with practical work.
  • Cross-references link learning outcomes to mathematical requirements and How Science Works (HSW).

2. Specification Content (Modules 1–6)

Module 1: Development of Practical Skills

  • 1.1 – Skills assessed in written exams: planning, implementing, analysis, evaluation.
  • 1.2 – Skills assessed in the Practical Endorsement: independent thinking, use of scientific methods, apparatus/techniques.

Module 2: Foundations in Biology

  • Cell structure, biological molecules, nucleotides, enzymes, membranes, cell division.

Module 3: Exchange and Transport

  • Exchange surfaces, transport in animals and plants.

Module 4: Biodiversity, Evolution and Disease

  • Communicable diseases, immunity, biodiversity, classification, evolution.

Module 5: Communication, Homeostasis and Energy

  • Neuronal/hormonal communication, homeostasis, excretion, photosynthesis, respiration.

Module 6: Genetics, Evolution and Ecosystems

  • Cellular control, inheritance, manipulating genomes, cloning, biotechnology, ecosystems.

3. Assessment Structure

  • Three written exams:
    1. Biological Processes (Modules 1, 2, 3, 5) – 37%
    2. Biological Diversity (Modules 1, 2, 4, 6) – 37%
    3. Unified Biology (all modules) – 26%
  • All include synoptic assessment and extended-response questions.
  • Practical Endorsement (Component 04):
    • Pass/fail reported separately.
    • Requires 12 practical activities across defined Practical Activity Groups (PAGs).
    • Assessed against Common Practical Assessment Criteria (CPAC).

4. Key Features

  • Co-teachable with AS Level (Modules 1–4 form AS content).
  • Emphasis on practical skills integrated throughout.
  • Mathematical requirements detailed (≥10% of exam marks).
  • How Science Works (HSW) themes embedded.
  • Supports progression to higher education and careers in science.

5. Support & Resources

  • Teaching resources: Delivery guides, topic packs, lesson elements.
  • Professional development: CPD events, online training.
  • Tools: Active Results (results analysis), ExamBuilder (past papers).
  • Contact: Science Subject Advisors via email/phone.

6. Administrative Details

  • Total qualification time: 360 hours.
  • Availability: Annual May/June exam series in England.
  • Retakes: Possible with carry-forward option for Practical Endorsement.
  • Accessibility: Reasonable adjustments and special consideration available.

7. Appendices

  • Mathematical requirements with formulae (recall and provided).
  • Health and safety guidelines.
  • Practical Endorsement details (PAGs, CPAC, activity examples).
  • Avoidance of bias and overlap with other qualifications.

8. Updates

  • Version 3.4 includes minor corrections and updates to guidance.
  • Changes are listed in a summary table at the end of the document.

This specification provides a comprehensive, skills-focused A Level Biology course with strong emphasis on practical competency, mathematical application, and real-world scientific understanding.
