No premium gate in the current IAT flow

Current official IAT pattern

The IAT 2026 brochure specifies a computer-based test with 60 single-correct questions: 15 each from Biology, Chemistry, Mathematics and Physics. The duration is 180 minutes, with +4 for a correct response, -1 for an incorrect response and 0 for unattempted questions.

  • 60 questions and 240 maximum marks
  • Four equal 15-question subject blocks
  • One correct option per question

Repository readiness and limits

All 539 stored questions have four options, an official answer, a solution and a topic. The inventory still carries paper-level limits: no 2020 paper, 59 questions in 2025, scan-review wording for 2018 and a provisional-key state for 2026.

  • Limitations remain visible on public inventory pages
  • Question and solution text stays in the protected flow
  • No performance or result claims are invented

Frequently asked questions

Are these original IAT mocks?

No. The current timed inventory consists of nine previous-paper simulations. Original mock count is zero.

How is the public inventory verified?

The loader requires each stored question to have a valid subject, four option keys, an official answer and a non-empty solution. Paper-level review limitations are reported separately.

Are answers or solutions exposed for SEO?

No. Public pages use counts, topic labels and workflow descriptions only. Question and solution payloads remain in the login-protected attempt and review routes.
