Frequently Asked Questions (FAQs) on UPSC Indian Forest Service Optional Syllabus

Question- What does it mean General Aptitude (CSAT) has been made qualifying”? Will only General Studies marks be counted for clearing Prelims examination?
Answer- Yes, provided you have scored at least 33% marks in CSAT paper.

Question- If I have given an attempt at Civil Services, is that counted in Indian Forest Service (IFS) Attempt too?
Answer- No. Your attempt for Civil service exam and Forest exam are counted separately. Even if you have exhausted all your CSE attempts, you can appear for IFS.

Question- Will my marks scored in Prelims affect my scores in Mains examination?
Answer- No. Prelims examination is meant to serve as a screening test only. Once you qualify Prelims, what you have scored before does not matter in Mains.
