- Paper-specific totals override generic pattern claims
- Official IISER sources remain authoritative
A fair comparison method
Compare subject totals, topic mix and response behaviour only after recording the corpus limitation. A 59-question stored paper should not be compared as if it were a complete 60-question source.

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.
