2026 — Paper not yet available: The AHSEC HS 1st Year exam was presumably held this year, but no verified question paper for this subject has been found from the sources we check. We publish only a paper we can verify against a real printed original — it will appear here once it is.

2021 — Exam cancelled (COVID-19): AHSEC cancelled the HS 1st Year (Class-11) examination in 2021 due to COVID-19; an order dated 7 May 2021 promoted all registered students to HS 2nd Year without sitting it. No annual question paper was conducted or printed that year, so none exists to publish.
