Are you preparing for your A-Level Biology exams and feeling the pressure? Don’t worry, we’ve got your back! The A-Level Biology (9700) syllabus covers a vast range of topics, and it’s important to focus your revision on key areas. This A-Level Biology Exam Guide will help you maximize your study time by highlighting the master topics to prioritize, offering last-minute tips to ensure you’re fully prepared, and giving you additional resources to download.
Here are the master topics to focus on for A-Level Biology, ensuring you’re well-prepared for the exam.
Master Topics to Focus on in A-Level Biology Exam Guide
1. Cell Structure and Function [AS]
- Key Areas: The ultrastructure of eukaryotic and prokaryotic cells, functions of cellular organelles, and the fluid mosaic model of membranes.
- Tip: Diagrams are often used in exams. Practice drawing cells and labeling organelles to ensure you can confidently answer structured questions about these topics.
2. Enzymes [AS]
- Key Areas: Enzyme activity, factors affecting enzyme reactions (temperature, pH, substrate concentration), enzyme inhibitors.
- Tip: Get familiar with interpreting graphs of enzyme activity under various conditions. Be ready to explain why changes in these factors affect the rate of reaction.
3. Transport Across Membranes [AS]
- Key Areas: Processes like diffusion, osmosis, facilitated diffusion, and active transport.
- Tip: Questions on practical applications are common. Understand how transport processes work within human and plant cells to prepare for data-based questions.
4. Genetics and Inheritance [A2]
- Key Areas: Mendelian genetics, genetic crosses, dihybrid crosses, sex linkage, pedigree analysis.
- Tip: Practice different types of genetic crosses, and ensure you understand complex inheritance patterns like autosomal linkage and sex-linked traits.

5. Photosynthesis and Respiration [A2]
- Key Areas: The light-dependent and light-independent reactions of photosynthesis, the Krebs cycle, and oxidative phosphorylation.
- Tip: Draw diagrams for both processes and understand the role of each step in energy production and carbon fixation. These processes are critical and often tested in essay questions.
6. Homeostasis [A2]
- Key Areas: The regulation of internal conditions, such as temperature, blood glucose, and osmoregulation, with focus on the kidney’s role in excretion.
- Tip: Be prepared to explain negative feedback mechanisms and hormonal control in homeostasis.
7. Variation and Evolution [A2]
- Key Areas: Darwin’s theory of evolution, genetic variation, speciation, and natural selection.
- Tip: Be ready to explain case studies or examples of natural selection and genetic variation, as well as population genetics questions.
8. Genetic Engineering [A2]
- Key Areas: DNA replication, genetic modification, cloning, PCR, and gene therapy.
- Tip: Focus on the applications of biotechnology in medicine and agriculture, such as GM crops or gene therapy.
9. Practical Skills and Data Analysis
- Key Areas: Drawing graphs, interpreting experimental data, and designing investigations.
- Tip: Paper 3 [AS] and Paper 5 [A2] both focus on practical skills. Make sure to practice drawing accurate biological diagrams, as well as interpreting and evaluating experiments.
By following these A-Level Biology exam guide tips, you’ll be fully prepared for exam day.
Last-Minute Tips from Your A-Level Biology Exam Guide
Master the Command Words:
- Understand what each question asks for by focusing on command words like “describe,” “explain,” and “evaluate.” Knowing the difference can help you tailor your responses effectively.
Review Diagrams and Graphs:
- Diagrams often appear in exams, so practice drawing and labeling important structures like cells, enzymes, and biochemical cycles. You should also be comfortable interpreting data from graphs.
Practice with Past Papers:
- Do as many past papers as you can, especially under timed conditions. Past questions will help you become familiar with the style and format of the exam.
- Download here for the latest 2024 A level exam papers.
Prioritize Your Weak Areas:
- Spend more time reviewing topics you struggle with. Use summary sheets, flashcards, or quick quizzes to reinforce weaker areas.
Get Plenty of Rest:
- Stay calm and focused. Avoid cramming the night before. Make sure you get enough sleep and take regular breaks during your study sessions.
