2025 — Paper not yet available: This year’s RBSE Class-11 exam was presumably held, but no verified question paper for this subject has been published by any source we check — the official rajeduboard.rajasthan.gov.in and the public past-paper archives. We publish only a paper we can verify against a real printed original — this one will appear here once it is.

2022 — Paper not yet available: This year’s RBSE Class-11 exam was presumably held, but no verified question paper for this subject has been published by any source we check — the official rajeduboard.rajasthan.gov.in and the public past-paper archives. We publish only a paper we can verify against a real printed original — this one will appear here once it is.

2021 — Exam not held (COVID-19): RBSE did not conduct the Class-11 (Senior Secondary Part-I) examination in 2021 at all — students were promoted without sitting any exam (a Rajasthan government decision, COVID-19 2nd wave). No question paper exists for this year because none was ever administered.

2020 — Paper not yet available: This year’s RBSE Class-11 exam was presumably held, but no verified question paper for this subject has been published by any source we check — the official rajeduboard.rajasthan.gov.in and the public past-paper archives.
