About the A-Level H2 Biology Exam
H2 Biology is a Singapore-Cambridge GCE A-Level subject examined in four papers. Its current syllabus, 9477, was first examined in 2026, the year SEAB examined the earlier syllabus, 9744, for the last time.
- Syllabus
- 9477, first examined in 2026
- Paper 1
- Multiple choice: 30 questions in 1 hour (15%)
- Paper 2
- Structured questions, including data-based or comprehension-type questions: 90 marks in 2 hours (30%)
- Paper 3
- Long structured and free-response questions, 75 marks in 2 hours (35%). Section A is built on stimulus material, such as a passage from a scientific journal; Section B is a choice of one 20-mark free-response question from two
- Paper 4
- Practical, 50 marks in 2 h 30 min (20%), with planning worth 4% of the subject
- Statistics
- Standard deviation, the t-test and the chi-squared test, with the equations and tables provided
- Subject combinations
- H1 and H2 Biology cannot be offered together
The syllabus has four core ideas and two extension topics, Infectious Diseases and the Impact of Climate Change on Animals and Plants, which together take up about 15% of the curriculum.
Common Challenges H2 Biology Students Face
Genetics at Molecular Depth
Gene expression, the genetics of viruses and bacteria, and genome organisation go far beyond O-Level inheritance.
Linkage and Interacting Genes
Dihybrid crosses with linkage, crossing-over and interaction between loci, then a chi-squared test on the results.
Cell Signalling and Respiration
Following a signal from reception through transduction to a response, and the stages of respiration in order.
Stimulus-Based Questions
Paper 3 sets questions on material students have not seen, sometimes adapted from a journal, which they must read quickly and use.
The 20-Mark Essay
Section B of Paper 3 is a free-response essay, marked partly on the quality of scientific argument and written communication.
The Practical Paper
Two and a half hours of planning, measuring, recording and evaluating, worth a fifth of the subject.
How Our Online H2 Biology Tutors Help
Pathways Drawn Stage by Stage
Transcription, translation and signal transduction sketched on a shared whiteboard, one stage at a time.
Genetics Problem Practice
Dihybrid crosses, linkage and chi-squared tests set out line by line until the method is routine.
Reading Stimulus Material
Practice with journal-style passages and data, picking out what each part of a question needs.
Essay Planning
Plans for 20-mark answers that link ideas across the core ideas, then feedback on the written essay.
Practical Paper Skills
Planning investigations, presenting data and evaluating limitations for Paper 4, alongside lab work in school.
Revision Through JC1 and JC2
Topic by topic before the promotional exams, then timed papers for the preliminary exams and the A-Level.
H2 Biology Topics Covered by Our Tutors
9477's content in the syllabus's own words. It is arranged by core idea and extension topic, not by JC1 and JC2.
Core Idea 1: The Cell and Biomolecules of Life
- The cell theory, membrane systems and organelles, and the structure of a typical bacterial cell
- Biomolecules and their functions, the fluid mosaic model of membranes, and the mode of action of enzymes
- Stem cells
Core Idea 2: Genetics and Inheritance
- DNA structure and function, and the central dogma from DNA to RNA to protein
- Eukaryotic chromatin, the genetics of viruses and bacteria, genome organisation and the control of gene expression
- DNA analysis and genomics, mutations, and the molecular biology of cancer
- Replication and division of nuclei and cells, and the effect of meiosis on chromosome number and variation
- Dihybrid crosses, linkage and crossing-over, interaction between loci, and the effect of genotype and environment on the phenotype
Core Idea 3: Energy and Equilibrium
- Photosynthesis as an energy-trapping process, and aerobic and anaerobic respiration
- Cell signalling: signal reception, transduction pathways and cellular responses
Core Idea 4: Biological Evolution
- The concept of the species and the neo-Darwinian revolution
- Variation, natural selection and evolution, the evidence of evolution, and classification
Extension Topics
- Infectious Diseases: the adaptive and innate immune system, genetic recombination, modes of viral and bacterial infection, vaccination and antibiotics
- Impact of Climate Change on Animals and Plants: human causes, effects on biodiversity, biomedicines and the global food supply, and the spread of dengue

Frequently Asked Questions About H2 Biology Tuition
Thinking of H2 Biology Tuition?
Is H2 Biology a Big Step Up From O-Level?
Yes. The syllabus treats O-Level Biology as its foundation and does not revisit it, then goes much further into molecular genetics, cell signalling and evolution.
Has the H2 Biology Syllabus Changed?
Yes. Syllabus 9477 was first examined in 2026 and is the one JC students sit from 2027; the earlier 9744 was examined for the last time in 2026.
Why Do Capable Students Still Lose Marks in H2 Biology?
The papers reward linking ideas across topics, such as genetics with evolution, and applying them to unfamiliar material. Answers that only recall facts rarely earn full marks.
When Should My Child Start H2 Biology Tuition?
Many start in JC1, when genetics and cell biology arrive in quick succession, or before the promotional exams. Others begin in JC2 to prepare for the practical, the preliminary exams and the A-Level.
Is H1 Biology an Option Instead?
Yes. H1 Biology (8876) covers the four core ideas with one extension topic, examined in two papers with no practical. Read about H1 Biology tuition.
Getting a Tutor
How Do I Request an H2 Biology Tutor?
Fill in the free form above with your child's level, class size and preferred times, and we'll reply on WhatsApp.

How Quickly Will We Hear Back?
We aim to reply on WhatsApp within one working day, and your child begins with a trial lesson.
Lessons
What Happens in an Online H2 Biology Lesson?
Your child joins a live Zoom lesson with cameras on. The tutor draws and labels processes on a shared screen and works through exam questions with them.
How Long Are H2 Biology Lessons?
Usually 1.5 or 2 hours, at a fixed time every week.
What If My Child Misses a Lesson?
Tell the tutor early; you're in direct contact. If it was a group lesson, the tutor can usually share the recording.
Others
How Much Does H2 Biology Tuition Cost?
It depends on the level and class size, and we confirm the fee on WhatsApp before the first lesson.
Are There Any Agency Fees?
No.
How Do We Stop Lessons After the A-Level?
Give one month's notice, out of courtesy to the tutor's planning. Payment throughout is by PayNow.
