Biology is among the most popular Cambridge subjects for Mauritius SC and IGCSE students — and one of the most reliably high-scoring when studied correctly. The key is learning to write answers in Cambridge's precise language: one mark per distinct point, specific terminology, no vague statements. This guide gives you free access to all IGCSE and O Level Biology past papers and shows you the exam technique that separates A* students from the rest.
Quick Answer:
IGCSE Biology (0610) and O Level Biology (5090) past papers for Mauritius SC students are available free at Aixampapers.com. The AI tutor provides mark-scheme-style answers for every Biology question — including data questions, diagram questions, and extended-response questions.
Biology Syllabuses Used in Mauritius
| Syllabus | Code | Level | Common in Mauritius |
|---|---|---|---|
| IGCSE Biology | 0610 | IGCSE | Private schools, international schools |
| O Level Biology | 5090 | O Level / SC | Most Mauritius state schools (SC exam) |
Content overlap is very high — approximately 85% of topics are identical. IGCSE Extended (0610) includes some additional content (e.g., more detail on genetics and biotechnology). Both syllabuses' past papers are effective revision material for Mauritius SC students.

Where Mauritius Students Lose the Most Marks in Biology
1. Imprecise Language in Extended Answers
Cambridge Biology mark schemes are very specific. "More oxygen is available" gets no mark — "the rate of aerobic respiration increases because more oxygen is available as a reactant" earns the mark. Students who write in vague terms consistently lose 1–2 marks per question.
Fix: After every extended-response question, compare your answer word-for-word with the mark scheme. Use Aixampapers AI tutor to see what a full-mark answer looks like for any question.
2. Genetics Crosses — Incomplete Working
Punnett square questions require you to: state the parental genotypes, draw the Punnett square correctly, state all offspring genotypes, and state the ratio (phenotypic and/or genotypic). Missing any one step loses marks even if the final ratio is correct.
3. Graph Questions in Paper 4 and Paper 6
Interpreting graphs (explaining shape, identifying anomalous results, calculating gradient) is tested every year. Students who have not practised data-analysis questions specifically are routinely surprised by these marks.
4. Photosynthesis vs Respiration Confusion
A common error: plants "do not respire." Plants respire continuously (aerobic respiration). During the day, they also photosynthesise at a faster rate than they respire. The net gas exchange appears to be CO₂ in, O₂ out — but both processes happen simultaneously. Cambridge specifically tests this distinction.
8-Week SC Biology Revision Plan for Mauritius Students
| Weeks | Topic Focus | Past Paper Target |
|---|---|---|
| 1–2 | Cells, enzymes, nutrition | 2 past papers (Paper 1 + Paper 2/4) |
| 3–4 | Transport, respiration, excretion | 2 past papers + 1 Paper 6 |
| 5–6 | Coordination, reproduction, genetics | 2 past papers + 1 Paper 6 |
| 7 | Ecology + mixed revision | 2 complete timed papers |
| 8 | Targeted weak-area revision using AI feedback | Past papers from weakest topics only |
Frequently Asked Questions
Where can I find free Cambridge Biology past papers for Mauritius SC?
Aixampapers.com provides free Cambridge Biology past papers — both IGCSE (0610) and O Level (5090) — with full marking schemes and AI step-by-step explanations for every question.
Is IGCSE Biology the same as O Level Biology for Mauritius SC?
Both syllabuses cover very similar content. IGCSE (0610) Extended includes slightly more detail on genetics and biotechnology. Mauritius SC students using O Level (5090) benefit from cross-practising IGCSE past papers, especially for the Extended tier questions.
How important is Paper 6 for IGCSE Biology?
Paper 6 (Alternative to Practical) is 40 marks and tests skills that are not directly tested in Papers 1, 2, or 4: planning experiments, drawing valid conclusions from data, identifying errors and improvements. It requires specific practice — students who ignore it consistently underperform their predicted grade.
What are the highest-mark topics in Cambridge Biology?
Topics that appear in nearly every Cambridge Biology exam session: transport (circulatory system, transpiration), genetics (monohybrid crosses, sex-linkage), photosynthesis and respiration, coordination (nervous system, hormones), and ecology (food webs, cycles). Mastering these 5 areas alone covers the majority of marks available.
