Everything we run for PSIR Optional
Three stages, depending on where you stand. Build the subject from zero in the Foundation, cover the whole syllabus through guided answer writing in OGP, or test what you already know in the Test Series. All fees below are inclusive of taxes.
PSIR Optional Foundation 2027
The complete subject from the ground up — two courses on the same 100-session base. Batch 2 starts 24 August 2026.
Magnus
Your optional, its application across the Mains, and support up to the Interview — at one fee, in any mode.
- 125 sessions — 100 core + 25 PSIR Praxis
- PSIR Dynamics, both phases
- Test Series with copy evaluation — included
- OGP Advanced next year — free
- OIGP interview guidance — free
Crucible
The same complete foundation, focused purely on the optional papers — in five plans, so you pay for the mode you actually use.
Upgrade from any Crucible plan to a higher plan or to Magnus within 30 days by paying only the difference. Existing ForumIAS students get a concession on both courses — ask the counselling desk before taking admission.
