H2 Biology
Four paper-favourite topics: photosynthesis, HIV, the nitrogen cycle, and Hardy-Weinberg. Pick one and play.
Photosynthesis & Calvin Cycle Game
LiveRubisco, photolysis, PSII and PSI, 3 CO2 per G3P, and why the cycle stalls in the dark.
Play tournamentHIV Life Cycle Game
Livegp120 fusion, reverse transcriptase, integrase, protease, and why combination ART works.
Play tournamentNitrogen Cycle Game
LiveWho fixes N2, nitrification vs denitrification, flooding, Haber-Bosch, and eutrophication.
Play tournamentHardy-Weinberg Equilibrium Game
Livep² + 2pq + q², the 1-in-10 000 carrier sum, five assumptions, and what inbreeding actually changes.

How to use these before the H2 paper
Reading a lecture deck on the Calvin cycle feels like you know it. Naming Rubisco under a timer is the test. Each game is a short tournament: fill-in-the-blank, disruptor, sequence, matching, a number, and a last scenario. Fail it, then play it again the next night.
These four topics keep showing up on 9744 because they are calculation-plus-mechanism, not a poster to memorise. Use them as a warm-up before a TYS paper, or as a redo after a messy prelim question.
What each game covers
- Photosynthesis — photolysis, PSII/PSI, Rubisco, 3 CO2 per net G3P, photorespiration when stomata close.
- HIV — attachment and fusion, reverse transcriptase, integrase, protease, and why one drug is not enough.
- Nitrogen cycle — fixation, nitrification, assimilation, ammonification, denitrification, fertiliser leak.
- Hardy-Weinberg — p² + 2pq + q², carrier frequency, the five assumptions, inbreeding vs allele frequency.
GCE A-Level games FAQ
Which A-Level is this for?
The Singapore-Cambridge GCE A-Level — SEAB H2 Biology syllabus 9744. That is the JC paper, not UK AQA, OCR, or Edexcel.
What can I play right now?
Four H2 tournaments: photosynthesis and the Calvin cycle, the HIV life cycle, the nitrogen cycle, and Hardy-Weinberg. Open one, answer under a clock, and try again until the sequence sticks.
Are the games free?
Yes. They run in the browser. No account, no email gate, no app install. Scores go to a public leaderboard under a handle you pick at the end.
How should I use these before prelims?
Play a topic until you can finish it without guessing — especially the calculations (3 CO2 per G3P, 2pq from 1 in 10 000, 78% N2). Then redo the ones you failed a day later. Use your lecture notes or a TYS after that, not instead of it.
What is H2 Biology 9744?
H2 Biology is the higher-level Singapore-Cambridge biology paper. Energy transfer, infectious disease, ecology, and population genetics keep coming back — these four games drill those.
