A Level Biology (9700) tests knowledge, application, and practical skills across five papers over AS and A2. Top grades come from precise biological terminology, correct genetic notation, and strong practical and evaluation technique.
Biology 9700 has five papers: multiple choice, AS structured, and a practical exam at AS, then A2 structured and a planning and evaluation paper at A2. A full A Level requires all five, with no paper choice. There is no written alternative to the practical, so lab work is compulsory.
This guide covers the five-paper structure, the high-yield topics, the practical and planning papers, genetic diagram technique, and the exact terminology examiners reward.
What Is the A Level Biology 9700 Paper Structure?
The qualification runs across five papers, three at AS and two at A2. Unlike non-science subjects, Biology includes dedicated practical assessment.
| Paper | Focus | Assesses |
|---|---|---|
| Paper 1 | Multiple Choice, 40 questions, AS content | Knowledge and application |
| Paper 2 | AS Structured Questions | Knowledge and application |
| Paper 3 | Advanced Practical Skills, in a lab | Practical skills |
| Paper 4 | A2 Structured Questions, A Level content | Knowledge and application |
| Paper 5 | Planning, Analysis and Evaluation | Practical reasoning |
Papers 1, 2, and 3 form the AS qualification. Papers 4 and 5 complete the A Level, with Paper 4 assuming the AS content as background knowledge.
A full A Level candidate sits all five papers with no option choice. You cannot enter or resit single papers in isolation, so plan your route with your school or exam centre.
What Are the High-Yield Biology Topics?
The syllabus is large, but some topics carry heavy marks and appear across multiple papers. Prioritise these while covering everything.
- Cell structure, membranes, and transport, the foundation for much of the course.
- Biological molecules, enzymes, and their mode of action.
- DNA, protein synthesis, and gene expression.
- Genetics, inheritance, and genetic diagrams at A2.
- Homeostasis, coordination, and the control systems of the body.
Genetics and inheritance reward precise work. A genetic cross must use correct notation, show the gametes, and explain the outcome. Sloppy notation loses marks even when the reasoning is right.

Chat on WhatsAppHow Does the Practical Paper 3 Work?
Paper 3 is a hands-on practical exam done in a laboratory. It tests real experimental skills, not written descriptions of them.
You handle familiar and unfamiliar biological material, use a light microscope, make measurements, and produce biological drawings. When unfamiliar techniques appear, you are given full instructions.
Practical work is worth a significant share of the AS marks, so it cannot be treated as an afterthought. There is no written alternative to this paper.
This matters for private candidates especially. Cambridge A Level Biology requires the lab-based practical, so you must arrange a centre that offers it. The private candidate A Level guide covers this requirement in detail.
What Is the Planning Paper 5?
Paper 5 is often misunderstood. It is not a hands-on practical like Paper 3, but a written paper testing practical reasoning.
It tests three skills: planning an investigation, analysing data, and evaluating results. You design a method, identify variables, and consider safety, then interpret data and judge reliability.
Examiner reports consistently flag Paper 5 planning and evaluation as weak areas. Students lose marks by writing vague methods or generic evaluations instead of specific errors and improvements.
Prepare for it through real practical experience, even though the exam is written. You cannot plan or evaluate an experiment well without having done experiments yourself.
How Do You Score Top Marks in Biology?
The gap between a B and an A star in Biology is usually precision, not knowledge. Five habits separate top answers.
- Use exact biological terminology from the syllabus, not everyday paraphrasing.
- Explain cause and effect fully, linking structure to function and one step to the next.
- Apply concepts to unfamiliar contexts, since questions often use new organisms or studies.
- Match your answer length to the mark tariff, giving one clear point per mark.
- Link topics synoptically at A2, connecting, for example, respiration to ecosystems.
Mark schemes reward specific keywords. A correct idea in vague words often scores nothing, so learn the precise phrasing Cambridge accepts. The A Level past papers and their mark schemes are the fastest way to learn this.
Aiming for the A star you need for medicine but stuck one grade below? Thinkerzz targets the terminology, application, and Paper 5 evaluation that lift Biology into the top band, live and 1 to 1.
Chat on WhatsAppFrequently Asked Questions
What Is the Syllabus Code for A Level Biology?
The Cambridge syllabus code for A Level Biology is 9700. It runs across five papers: multiple choice, AS structured, a practical, A2 structured, and a planning and evaluation paper.
How Many Papers Are in A Level Biology 9700?
Five. Papers 1, 2, and 3 at AS, then Papers 4 and 5 at A2. A full A Level candidate sits all five, with no paper option choice.
Is There a Practical Exam in A Level Biology?
Yes. Paper 3 is a hands-on laboratory practical testing real experimental skills. There is no written alternative, so lab work is compulsory for the qualification.
What Is the Difference Between Paper 3 and Paper 5?
Paper 3 is a hands-on practical done in a lab. Paper 5 is a written paper testing planning, analysis, and evaluation skills, though it still requires real practical experience.
Can Private Candidates Take A Level Biology?
Yes, but they must arrange a centre offering the lab-based Paper 3, since there is no written alternative to the practical. This is the main challenge for private science candidates.
Why Do I Lose Marks Despite Correct Answers?
Usually on terminology. Mark schemes reward exact biological terms and precise phrasing. A correct idea in vague or everyday words often scores nothing.
How Do I Draw Genetic Diagrams Correctly?
Use correct notation for alleles, clearly show the parental genotypes and gametes, and explain the outcome. Correct notation and full working are essential for the marks.
What Are the Weakest Areas Reported by Examiners?
Paper 5 planning and evaluation, vague terminology, and applying knowledge to unfamiliar contexts. Targeting these directly is the fastest way to raise a grade.
How Important Is Practical Work for the Written Papers?
Very. Real lab experience improves Paper 3 directly and is essential for Paper 5 planning and evaluation. It also deepens understanding that helps in the theory papers.
Is A Level Biology Required for Medicine?
Yes. Biology is essential for medicine, dentistry, and pharmacy, usually alongside Chemistry. It is one of the core pre-medical subjects for the MDCAT and admission.
Is A Level Biology Hard?
It is content-heavy and demands precise terminology and strong practical skills. Students who learn exact vocabulary and practise past papers with mark schemes perform best.
How Do I Prepare for the Planning Paper?
Do real experiments, then practise past Paper 5 questions. Learn to state variables, write clear methods, and give specific errors and improvements rather than generic ones.
