Take an older SBO paper (e.g., from 5–6 years ago) and attempt it without a timer. Use your textbooks or Campbell Biology if you get stuck. This phase helps you identify massive gaps in your baseline knowledge before you begin intensive revision. Phase 2: Topical Integration
For students aiming to top the national cohort, this advanced textbook provides deeper insights into cell signaling and biochemistry questions that frequently appear in modern papers. Where to Find SBO Past Papers
You misread the graph, chart, or text prompt.
If you are a lower secondary student, note that SJBO also does not release papers, but organizers explicitly recommend using IBO past papers as the primary reference. 🔬 Exam Format & Strategy Round 1: Theory Test Structure: Roughly 100 Multiple Choice Questions (MCQs). Duration: 3 hours.
Singapore Biology Olympiad (SBO) Singapore Junior Biology Olympiad (SJBO)
The Theory round challenges you to process complex, multi-part questions under strict time constraints. Simulated mock exams build your pacing.
Go deep into proteomics, signaling pathways, and advanced microscopy techniques.
: Roughly 35% O-Level, 35% A-Level, and 30% IBO standard. Singapore Biology Olympiad (SBO) :
The top-performing students from the Theory round advance to the Practical round. Past practical tasks focus on advanced laboratory skills, including: Biochemical assays and spectrophotometry Plant anatomy dissection and micro-troweling Animal anatomy, histology, and physiological simulations
“You can talk?” Lian breathed.
Two to three weeks after completing a paper, go back and re-attempt only the questions you got wrong in Phase 2. This ensures that you have actually internalized the concepts and corrected your thinking process, rather than just memorizing the correct letter option. Essential Companion Resources
