Previous year papers
100 questions across all yearsOfficial sample papers
Free sample papers Science Olympiad Foundation (SOF) publishes on its own site for the 2026-27 exam. They are the body's own practice papers, not previous years' papers. Each link opens the body's own file.
Previous year paper practice: each year is a set of PYQ-pattern questions — freshly worded in the pattern of that year's paper, not the paper itself. Every card shows how many it holds against the real paper's count.
