Practical skills are integrated directly into the theoretical modules, ensuring students understand the "why" behind experimental techniques. Student and Expert Perspective Switching to OCR Biology A from AQA A Level Biology for OCR A
Development of practical skills in biology (assessed across all papers). Module 5: Communication, homeostasis, and energy
Topics are structured to build foundational knowledge first (Module 2) before moving into complex systems, making it easier for students to see the "big picture" of biological concepts. Student and Expert Perspective Switching to OCR Biology
