Where Tutix is today
A ready-made A Level Biology program is planned and not available yet. You can start a A Level Biology class now: the tutor teaches live from your syllabus or notes. Ready-made programs exist for other courses.
The qualification
Cambridge International AS & A Level Biology is syllabus 9700. The syllabus for exams in 2025 to 2027 is the 2025-2027 syllabus; a 2028-2030 syllabus follows. Exams are in the June and November series, and in March for centres in India. AS candidates are eligible for grades a to e (in lower case) and A Level candidates for A* to E.
The papers
| Paper | Title | Time | Marks | AS share | A Level share |
|---|---|---|---|---|---|
| 1 | Multiple choice (AS content) | 1 h 15 | 40 | 31% | 15.5% |
| 2 | AS structured questions | 1 h 15 | 60 | 46% | 23% |
| 3 | Advanced Practical Skills | 2 h | 40 | 23% | 11.5% |
| 4 | A Level structured questions (A Level content; AS knowledge required) | 2 h | 100 | Not offered | 38.5% |
| 5 | Planning, Analysis and Evaluation | 1 h 15 | 30 | Not offered | 11.5% |
AS is Papers 1, 2 and 3 taken together in one series. The A Level is all five papers, staged over two years or all in one series. Papers 3 and 5 test practical skills in an exam, not as coursework. Electronic calculators are allowed in the exams.
What the marks test
At both AS and A Level, Cambridge gives 40% to knowledge and understanding, 40% to handling, applying and evaluating information and 20% to experimental skills and investigations. Cambridge calls these weightings approximate.
| Assessment objective | AS Level | A Level |
|---|---|---|
| AO1 Knowledge and understanding | 40% | 40% |
| AO2 Handling, applying and evaluating information | 40% | 40% |
| AO3 Experimental skills and investigations | 20% | 20% |
| Assessment objective | Paper 1 | Paper 2 | Paper 3 | Paper 4 | Paper 5 |
|---|---|---|---|---|---|
| AO1 Knowledge and understanding | 50% | 50% | 0% | 50% | 0% |
| AO2 Handling, applying and evaluating information | 50% | 50% | 0% | 50% | 0% |
| AO3 Experimental skills and investigations | 0% | 0% | 100% | 0% | 100% |

Example
A Level Biology · Photosynthesis · Limiting factors
Explain why the rate of photosynthesis stops increasing as light intensity rises. [2 marks]
That is the observation, not the explanation. Name what has happened to light as a factor, and name one factor that now limits the rate.
A sample written to show how a class sounds. The scores show how the exam would credit each answer. Not a real learner.
What a ready-made program adds, and what it costs
Ready-made programs, such as IGCSE Physics, come with lessons and questions reviewed in advance, at five levels. The Free plan includes 45 live class minutes a month with no card; see the plans.
The twelve ready-made programs are drawn to scale, with a real lesson to read, on the Programs page.
Questions people ask

Not ready-made yet; it is planned. Today you can start an A Level Biology class: type the subject, attach your syllabus or notes, and the tutor builds the classes around them.
What topics are in A Level Biology?
AS Level covers Cell structure, Biological molecules, Enzymes, Cell membranes and transport, The mitotic cell cycle, Nucleic acids and protein synthesis, Transport in plants, Transport in mammals, Gas exchange, Infectious diseases and Immunity. The A Level adds Energy and respiration, Photosynthesis, Homeostasis, Control and coordination, Inheritance, Selection and evolution, Classification, biodiversity and conservation and Genetic technology. Both levels also assess practical skills.
What papers are in A Level Biology?
Paper 1, Multiple choice, 1 h 15; Paper 2, AS structured questions, 1 h 15; Paper 3, Advanced Practical Skills, 2 h; Paper 4, A Level structured questions, 2 h; Paper 5, Planning, Analysis and Evaluation, 1 h 15.
What is the difference between AS and A Level Biology?
AS is Papers 1, 2 and 3 taken together in one series. The A Level is all five papers, staged over two years or all in one series. Papers 3 and 5 test practical skills in an exam, not as coursework.
Which A Level Biology syllabus should I follow?
The syllabus for exams in 2025 to 2027 is the 2025-2027 syllabus; a 2028-2030 syllabus follows. Check the syllabus your school or exam centre is entering you for.
