2021 — Exam cancelled (COVID-19): RBSE cancelled the Class-12 Senior Secondary Examination in 2021 due to COVID-19 (a Rajasthan State Council of Ministers decision); students were promoted via internal assessment. No exam was administered that year, so there is no genuine previous-year paper to publish.

2019 — Paper not yet available: This year’s exam was 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.

2018 — Paper not yet available: This year’s exam was 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.
