The Singapore Junior Biology Olympiad (SJBO) does not publicly release its past year exam papers. To maintain the competition's integrity, teachers must sign a non-disclosure agreement (NDA), and the online theory test is only accessible via unique passwords during the designated three-hour window. Official Competition Details
The Singapore Junior Biology Olympiad (SJBO) is a prestigious national competition for secondary school students, jointly organized by the Singapore Institute of Biology and Science Centre Singapore. It serves as a platform for students to challenge themselves far beyond the standard curriculum. The competition has seen a surge in participation, with 2,967 students from 115 schools taking part in the 2025 theory round alone. singapore+junior+biology+olympiad+past+papers+exclusive
