🔍 AQA GCSE Biology Paper 2 2026: What Should Students Revise?
AQA GCSE Biology Paper 2 covers some of the most application-heavy areas of the GCSE Biology course. Students often search for AQA Biology Paper 2 predictions because the paper can include longer written answers, data analysis, graphs, required practical-style questions and synoptic links between topics.
The main areas students should revise for AQA GCSE Biology Paper 2 2026 include:
✅ Homeostasis and response
✅ The nervous system, reflex arcs and synapses
✅ Hormones, insulin, glucagon and blood glucose control
✅ Thermoregulation and body temperature control
✅ Inheritance, variation and evolution
✅ Genetic engineering and protein synthesis
✅ Natural selection, speciation and genetic drift
✅ Classification and evolutionary trees
✅ Ecology, decomposition, carbon cycle and eutrophication
These topics are high-yield because they regularly test both knowledge and application. A student may know the definition, but still lose marks if they cannot apply it to a graph, table, experiment or unfamiliar biological example.
🧠 AQA GCSE Biology Paper 2 Predicted Topics for 2026
Based on the structure of our AQA GCSE Biology Paper 2 2026 predicted paper, students should pay close attention to the following predicted topic areas.
1. Nervous System, Reflex Arcs and Synapses
The nervous system is a strong Paper 2 topic because it can be tested through diagrams, calculations and written explanations. Students should revise:
Motor neurones and sensory neurones
Myelin sheath function
Reflex actions and reflex arcs
Speed calculations for nerve impulses
Synapses and neurotransmitters
How drugs can affect synaptic transmission
This is a good topic for AQA Biology Paper 2 predictions because it combines factual recall with application. A student may need to explain how an impulse crosses a synapse or calculate the speed of a nerve impulse using distance and time.
2. Blood Glucose, Insulin, Glucagon and Diabetes
Blood glucose control is one of the most important Paper 2 homeostasis topics. Students should revise how the body responds after blood glucose rises and how hormones restore blood glucose to normal.
Key areas include:
Insulin lowering blood glucose
Glucagon increasing blood glucose
Type 2 diabetes
Cell sensitivity to insulin
Interpreting blood glucose graphs
Metformin and blood glucose control
Students often lose marks here because they write vague answers such as “insulin controls glucose.” A stronger answer explains that insulin causes glucose to move from the blood into cells and can cause glucose to be converted to glycogen in the liver and muscles.
3. Thermoregulation and Skin Responses
Thermoregulation is another strong predicted topic for AQA GCSE Biology Paper 2 2026. Students should understand what happens when the body is too hot and too cold.
Revise:
Sweating and evaporation
Vasodilation
Vasoconstriction
Shivering
Heat loss by radiation and conduction
Percentage increase calculations involving body temperature
This topic is useful for predicted papers because it can be tested using labelled diagrams, calculations and explanation questions.
4. Inheritance, Incomplete Dominance and Variation
Inheritance questions are commonly searched by students looking for AQA GCSE Biology predicted topics because they can involve Punnett squares, ratios, probability and extended explanations.
For Paper 2, students should revise:
Punnett squares
Alleles and genotypes
Phenotype ratios
Incomplete dominance
Sexual reproduction and variation
Why actual results can differ from expected ratios
A good predicted paper should not only test simple dominant and recessive inheritance. It should also test students on more challenging inheritance contexts, such as incomplete dominance and variation.
5. Protein Synthesis and Genetic Engineering
Protein synthesis and genetic engineering are high-value revision areas for AQA GCSE Biology Paper 2. These topics often test step-by-step processes and require precise scientific language.
Students should revise:
DNA base sequences
mRNA codons and tRNA anticodons
Mutations and their effect on proteins
Producing insulin using genetically engineered bacteria
Restriction enzymes, plasmids and bacterial cells
Advantages and disadvantages of genetic engineering
This is a strong area for predictions because students often know the general idea but lose marks by missing key steps, such as cutting DNA, inserting the gene into a plasmid and placing the recombinant plasmid into bacteria.
6. Natural Selection, Evolution and Genetic Drift
Natural selection is one of the most important Biology Paper 2 topics. It can be tested using animal populations, allele frequency, selection pressure and data over time.
Students should revise:
Variation within a population
Selection pressure
Survival and reproduction
Allele frequency changes over generations
Genetic drift
Small populations and chance effects
For top marks, students should explain the full sequence: variation exists, some individuals are better adapted, they survive and reproduce, and the beneficial allele becomes more common over generations.
7. Classification, Speciation and Evolutionary Trees
Classification is another topic students should not ignore. It can appear as a short recall question or as a longer application question involving evolutionary trees and common ancestors.
Revise:
Evolutionary trees and common ancestors
Speciation by geographical isolation
Linnaean classification
Limitations of physical classification
The three-domain system
Archaea, Bacteria and Eukaryota
This is a useful predicted topic because it can test both recall and explanation. Students should be able to explain why two species are closely related and how geographical isolation can eventually lead to new species.
8. Ecology, Decomposition, Carbon Cycle and Eutrophication
Ecology questions often involve tables, graphs, calculations and long written answers. This makes them important for AQA GCSE Biology Paper 2 predicted topics.
Students should revise:
Decomposition and microorganisms
Waterlogged soil and oxygen availability
Carbon cycle
Respiration by decomposers
Eutrophication
Fertiliser runoff and oxygen depletion
Graph plotting and mean rate calculations
Students should practise writing the full sequence for eutrophication: fertiliser enters water, algae grow rapidly, light is blocked, plants die, microorganisms decompose dead material, oxygen is used up and fish die.
9. Genetic Bottlenecks, Founder Effect and Inbreeding
More challenging Biology Paper 2 questions may test genetic variation in small populations. These questions are useful for Higher Tier students aiming for strong grades.
Students should revise:
Genetic bottlenecks
Founder effect
Inbreeding
Reduced genetic variation
Inherited disease alleles
Small population effects
This is a good topic for a Higher Tier predicted paper because it tests deeper understanding of inheritance, evolution and population genetics.

This can make revision feel easier than the real exam because the questions are familiar.
A predicted paper gives students fresh unseen practice. It helps test whether you can apply Biology knowledge to a new question, rather than simply remembering an old answer.
A good predicted paper helps with:
✅ Fresh exam-style practice
✅ Predicted topics and likely question styles
✅ Timing practice
✅ Long-answer structure
