Top Exam Tips for A-Level Biology

Expert strategies for A-Level Biology excellence

1
Master Scientific Terminology

A-Level Biology requires precise terminology. Learn exact definitions and use appropriate scientific language in all answers.

2
Practice Extended Response Questions

Long-answer questions test your ability to construct coherent arguments. Plan your answer, use paragraphs, and link ideas logically.

3
Understand Statistical Tests

Know when to use t-tests, chi-squared tests, and correlation coefficients. Practice calculating and interpreting results.

4
Learn All Practical Techniques

15% of marks relate to practical skills. Know how to use microscopes, prepare slides, perform dissections, and evaluate methods.

5
Draw and Annotate Diagrams

Practice drawing key diagrams (cells, organs, cycles). Use pencil, draw clear lines, and label accurately with leader lines.

6
Link Topics Together

A-Level Biology is interconnected. Show examiners you understand links between topics (e.g., respiration connects to transport, photosynthesis, and ecology).
