Singapore Biology Olympiad Past Papers May 2026

Preparing for the Singapore Biology Olympiad (SBO) or its junior counterpart, the Singapore Junior Biology Olympiad (SJBO), requires a focus on application and higher-order thinking. 1. Where to Find Past Papers

Where to Find Authentic SBO Past Papers

Official full papers are not publicly archived in bulk by the Singapore Ministry of Education. However, you can obtain them through:

Singapore Junior Biology Olympiad (SJBO): Launched in 2016 for Secondary 2-4 students (ages 14-16) to complement the main SBO.

1. Recall-type questions (40%): These questions required students to recall factual information from memory.
2. Application-type questions (30%): These questions required students to apply their knowledge to a specific scenario or context.

6. A 6-Week Past Paper Schedule (Assuming 1 paper/week)

| Week | Focus | Activity | | :--- | :--- | :--- | | 1 | Baseline | Take oldest available paper (e.g., SBO 2015). Score it. List bottom 3 topics. | | 2 | Cell & Genetics | Study gaps. Take Cell & Genetics sections only from another paper. | | 3 | Physiology | Study gaps (Taiz & Guyton). Take Physiology sections from a third paper. | | 4 | Ecology & Evolution | Study gaps (Ricklefs). Take Ecology & Evolution sections. | | 5 | Full Mock | Take a recent paper (e.g., SBO 2022). Strict timing. | | 6 | Final review | Review only your Missed Concept Cards. Do 50 random questions from any paper. |

School Science Departments: Most Junior Colleges (JCs) in Singapore have internal archives of SBO papers from previous decades. Check with your Biology teachers or Olympiad coordinators.
