27 May Preparing for UPSC Mains & IFoS
UPSC Prelims 2025 Over? Start Preparing for Mains & IFoS Without Waiting for Results!
The UPSC Civil Services Preliminary Exam 2025 is done and dusted. While most aspirants are anxiously waiting for the results, those serious about cracking UPSC CSE Mains or Indian Forest Service (IFoS) Mains know there’s no time to lose.
Whether you’re aiming for IAS or IFS, the golden rule is simple: Don’t wait for the results — start your Mains preparation now. With barely 3–3.5 months in hand, this is the most decisive phase of your preparation journey.
? Why You Should Not Wait for Prelims Results
- UPSC never gives much time between Prelims result and Mains — usually 80–90 days.
- The syllabus for Mains is vast and analytical — not possible to complete last minute.
- IFoS Mains and CSE Mains often require different optional subjects and writing styles.
Early movers have a serious edge. So if you think you did reasonably well in Prelims, start preparing now!
? Mains 2025 Preparation Strategy for UPSC CSE
1. Understand the Syllabus Thoroughly
The CSE Mains consists of 9 papers — 4 GS papers, Essay, 2 optional papers, and 2 qualifying papers (English & Indian language). Build your plan around GS + Essay + Optional.
2. Target-Based Daily Routine
- Morning: GS Paper (History, Polity, etc.)
- Afternoon: Optional subject (as per your background)
- Evening: Essay and answer writing practice
3. Join a Mains Test Series
Practice is key. Choose a test series with proper feedback (like the one offered by PlutusIAS). Try to write at least 3–4 answers daily.
4. Current Affairs Integration
Make notes from The Hindu, PIB, or monthly compilations and link them with GS topics (ethics, governance, society, IR, etc.)
5. Optional Subject Focus
Don’t ignore optional — it can make or break your selection. Revise notes, practice previous year questions, and solve mock tests.

? Special Focus: IFoS Mains Preparation Strategy
If you ticked the IFoS option in the prelims form and your CSAT went well, it’s wise to start parallel preparation for IFoS Mains.
1. Know the Pattern
- General English
- General Knowledge
- Two Optional Subjects (4 Papers)
Optional subjects include Agriculture, Forestry, Botany, Zoology, Geology, Mathematics, Statistics, etc. Choose wisely based on your academic background.
2. Subject-Wise Planning
- Revise optional subjects with emphasis on diagram-based, technical answers.
- Practice essay, précis, and grammar for General English.
- General Knowledge is static + current — similar to GS1 and GS3.
3. Resource Optimization
Use integrated resources for both CSE and IFoS where possible — e.g., GS Paper for CSE and General Knowledge for IFoS.
? Suggested 90-Day Planner (June to September 2025)
- June: GS Paper 1 & 2 + Optional Subject 1
- July: GS Paper 3 & 4 + Optional Subject 2
- August: Essay + Ethics Case Studies + Full-Length Test Papers
- September: Rapid revision + Mock papers + Optional test series
? Pro Tip: One Strategy Does Not Fit All
Make a personalized plan. If you’re targeting both CSE and IFoS, divide your day between GS + Optional + English/Essay as per your strengths.
? Final Words
“The best time to start was yesterday. The next best time is today.”
Don’t wait for the result to dictate your discipline. Most toppers start preparing for Mains the very next day after Prelims. Join that league — study smart, write more, revise well, and stay focused.
If you’re looking for expert guidance and Mains mentorship, explore hybrid programs like those at PlutusIAS, where limited batch size and personalized feedback make a difference.
All the best, future officers!
