Frequently Asked Questions

Does this cover the complete syllabus for all 4 optionals?
Yes — each of the four subjects in this bundle is EVOLUTION Institute’s full-syllabus set for that optional. The Forestry, Agriculture, Botany, and Zoology notes cover their respective IFoS (and UPSC CSE) optional syllabi completely.

Which optional combination is most common in IFoS?
Forestry is taken by almost all IFoS aspirants as a first optional since it is the most IFoS-specific subject. The second optional varies — Agriculture, Zoology, Botany, and Chemistry are popular choices depending on the candidate’s graduation background. This bundle covers the top three non-Forestry choices alongside Forestry itself.

Can I use this for UPSC CSE as well?
Agriculture, Botany, and Zoology are all valid optional subjects in UPSC CSE Mains. The Agriculture, Botany, and Zoology notes in this bundle are calibrated for both UPSC and IFoS. The Forestry notes are IFoS-specific (Forestry is not a UPSC CSE optional).

Is this better value than buying individually?
Yes — the four subjects individually cost ₹399 + ₹500 + ₹500 + ₹500 = ₹1,899. The bundle is priced at ₹999, saving ₹900 (47% off the combined individual price).
