2021 — Likely no exam held (COVID-19): JAC confirmed the Class-12 (Intermediate 2nd Year) examination was cancelled in 2021 due to COVID-19, and no source we check lists any 2021 paper for Class-11 either — strongly suggesting the same cancellation applied, though no source names Class-11 explicitly. We publish only a paper we can verify against a real printed original, so we show none rather than an unconfirmed copy.

2018 — Paper not available: The JAC Intermediate 1st Year exam was presumably held this year, but no verified question paper for this subject has been published by any source we check — the official archive and the public past-paper archives. We publish only a paper we can verify against a real printed original — it will appear here once it is.
