Questions about these papers

How are the IRSOD papers organised?
By chapter, in the order the manual prints them. Longer chapters are split into several short papers so one sitting does not have to cover a whole chapter. Shorter chapters are grouped into combined papers, marked on this page.
Is this the official IRSOD syllabus?
No. Mock Test Mitra is a practice platform, not a conducting authority. Which chapters your paper draws on is set by your zonal notification, which can differ between zones and cycles. This page lists what we have written practice for.
Do the papers reflect the latest edition and correction slips of the IRSOD?
We cannot promise that. Most explanations cite the chapter or paragraph of the manual they rely on, but we have not checked every answer against the edition and correction slips currently in force. Check the current manual before relying on any answer.
