How to use these papers
- Read the syllabus for your class first, then try one official paper under the real time limit, without help.
- Mark it with the official answer key, and list each question you got wrong by topic. That list is what to study next.
- Try the next paper a week or two later and compare which topics are still on your list.
- Your school registers you and tells you which of SOF's dates it has chosen.
Good to know
- SOF's IHO dates page carries the heading "ISSO" by mistake (23 Oct 2026); the dates on it are the IHO's.
- SOF's sample-paper pages also advertise a publisher's paid practice books. Shishya does not copy or link those books; the sample papers linked here are SOF's own free PDFs.
