GCSE Combined Science Revision Timetable
GCSE Combined Science feels crowded because Biology, Chemistry and Physics all need space, but treating them as three unrelated subjects creates an unmanageable timetable. A better plan rotates the sciences while keeping practical and maths skills in every cycle.
For AQA Combined Science: Trilogy 8464, plan around six papers: Biology 1 and 2, Chemistry 1 and 2, and Physics 1 and 2. Each week should include all three sciences, required-practical retrieval, calculations or data work, and a mixed error-repair session. Check your own board before copying the topic split.

Build my study planBuild the timetable from the six-paper map
AQA Combined Science: Trilogy has six written papers, two each for Biology, Chemistry and Physics. Each paper lasts 1 hour 15 minutes and contributes about one sixth of the qualification. That makes it risky to ignore one science for several weeks, even when another feels more urgent.
| Session | Main task | Example output |
|---|---|---|
| Biology | Retrieve one topic, then answer application questions | A marked diagram, explanation or data response |
| Chemistry | Combine concepts with equations or calculations | A topic set with a calculation error log |
| Physics | Practise concepts, equations, units and graphs | A mixed calculation and explanation set |
| Practical and repair | Review one required practical and recurring errors | Variables, method, graph and evaluation notes |
A four-week Combined Science rotation
- Week 1: Biology Paper 1, Chemistry Paper 1 and Physics Paper 1 topic checks.
- Week 2: Biology Paper 2, Chemistry Paper 2 and Physics Paper 2 topic checks.
- Week 3: required practicals, maths skills, graphs, units and weak-topic questions across all three sciences.
- Week 4: timed sections or papers, followed by marking and targeted repair sessions.
Do not revise required practicals as recipes
AQA states that written-exam questions draw on practical knowledge and that at least 15% of the overall marks relate to practical work. Practise why steps are used, how variables are controlled, how data should be presented and how a method could be improved.
Use one error log with clear labels
Record the science, paper, topic, question skill and cause of the mistake. A label such as “Physics P1 - electricity - unit conversion” is schedulable; “revise electricity” is too broad. Repeat the exact skill a few days later, then retire it only after a fresh question is correct.
Balance Combined Science with everything else
Add Biology, Chemistry and Physics as separate subjects in My Study Plan so each can have its own importance and confidence score. The planner can distribute sessions around school, homework and rest days, then export the timetable as a PDF or calendar file.

Common questions
How do I make a GCSE Combined Science revision timetable?
Give Biology, Chemistry and Physics at least one slot in each weekly cycle, then add required-practical work, calculations, timed questions and an error-repair session.
How many papers are there in AQA Combined Science: Trilogy?
There are six written papers: two Biology, two Chemistry and two Physics papers. Each lasts 1 hour 15 minutes and is worth 16.7% of the GCSE.
Should I add Combined Science as one subject in a planner?
For better prioritisation, add Biology, Chemistry and Physics separately so a weaker science can receive more time without hiding the others.
