What the exam asks of you
AQA GCSE Combined Science: Trilogy (specification 8464) is worth two GCSEs and is examined by six papers, two for each science, each 1 hour 15 minutes and 70 marks. The biology content is sat as Biology Paper 1 and Biology Paper 2, together a third of the qualification. This is the Foundation tier: grades 5-5 to 1-1 are available, and the higher-tier content is not examined.
Trilogy covers three sciences in the time most schools give to two, which makes it the qualification where forgetting costs the most. Working one subtopic at a time is what keeps the biology third from slipping while the other two are being taught.

What is in the guide
All topics
Every topic has its own page with its subtopics, what it covers and sample questions.
Sample questions
Taken from the guide. Answer each one closed book first, then open the answer.
-
The photosynthesis reaction and the uses of glucose
Into which structures of a plant cell is energy transferred by light during photosynthesis?
Show the answer
The chloroplasts. -
Eukaryotes and prokaryotes
What type of cell is a bacterial cell?
Show the answer
A prokaryotic cell. -
Levels of organisation in an ecosystem, and what organisms need
What is an ecosystem?
Show the answer
The interaction of a community of living organisms with the non-living parts of their environment. -
Homeostasis
Apart from enzyme action, what else does homeostasis keep at its optimum?
Show the answer
All the other functions carried out by the cells of the body. -
Communicable (infectious) diseases
Describe how a pathogen carried in the air passes from one person to another.
Show the answer
An infected person coughs or sneezes out droplets containing the pathogen, and another person inhales them. -
Sexual and asexual reproduction
Name the male gamete and the female gamete in animals.
Show the answer
The sperm cell is the male gamete and the egg cell is the female gamete. -
Levels of organisation, and how enzymes work
List the levels of organisation in a multicellular organism, from the smallest to the largest.
Show the answer
Cells, then tissues, then organs, then organ systems, then the whole organism.
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.

Questions students ask first
I do the separate sciences, not Combined Science.
Then you need a different guide. The separate sciences are examined on their own specifications, Biology (8461) among them, and they carry more biology than Trilogy does.
The one you want is AQA GCSE Biology, Foundation.
Trilogy or Synergy? My school mentioned both.
AQA runs two combined science specifications. Combined Science: Trilogy is 8464, taught as three separate sciences, and that is the one this guide set covers. Combined Science: Synergy is 8465 and is taught as four integrated topics instead.
The code is on your exam timetable. If it says 8465 this is not your specification.
Higher or Foundation. Which do I need?
This is the Foundation tier guide, offering grades 5-5 to 1-1 of the double award.
AQA sits the same numbered papers at either tier, so Biology Paper 1 and Biology Paper 2 is what you sit whichever tier you are entered for. The tier changes the content and the grades available, not the paper numbers.
Your teacher decides the entry, usually during Year 11. If you are moved up to Higher you will need the Higher guide, which adds the higher-tier content.
Which topics are on which paper?
Biology Paper 1 covers Cell Biology, Organisation, Infection and Response, Bioenergetics. Biology Paper 2 covers Homeostasis and Response, Inheritance, Variation and Evolution, Ecology.
The two papers divide the content between them. The full breakdown is here.
