Prelims Examination is often called the “Elimination Round” — not because it merely filters non serious candidates, but because it demands a calculated mix of clarity, strategy, and composure under pressure.
With lakhs of aspirants attempting the exam each year and barely around 2-3% making it to the Mains stage, a smart, evidence-based approach is indispensable.
We prepared a holistic roadmap to not just clear but excel in the UPSC Prelims.
Understanding the Prelims Exam Structure
The Prelims consists of two papers:
General Studies Paper I (GS-I) – 100 Questions | 200 Marks | Qualifying for Mains Cut-off
General Studies Paper II (CSAT) – 80 Questions | 200 Marks | Qualifying (33% minimum)
Key Facts:
- Negative marking: 1/3rd per wrong answer
- Marks of GS Paper I decide your cut-off .
Why Prelims is Tricky — Decoding UPSC’s Mindset
Based on UPSC annual reports and interviews of successful candidates:
- Questions test conceptual clarity over rote memorization
- Increasing emphasis on analytical application and current affairs
- Often unpredictable weightage across subjects year-to-year
- Example: In 2020, Environment contributed 15-18 questions; in 2022, it surged to over 22.
Step-by-Step Strategy to Score Well:
1. Build a Strong Conceptual Foundation

4. Master the Art of Elimination
In a UPSC paper where 50%+ questions seem alien, elimination is your best friend. But remember UPSC eliminated the scope for elimination.

- Prefer moderate, factual options
- Relate options to known facts to infer possibilities
Practice daily with 15-20 MCQs. La Excellence provides daily quiz of 10 questions with a value addition. Solving such questions daily and discussing with your peers can build strong conceptual clarity.
5. Create a Focused Revision Plan:
Toppers’ Insight:
Most toppers revise static content 4-5 times before prelims.
Structure:
- Last 90 days: 2 revisions of core static subjects
- Last 30 days: Revise mocks’ mistakes + value-added notes + current affairs
- Use one consolidated notebook for quick revision.
6. Mental Conditioning and Resilience:
Why?
Because Prelims is as much about handling uncertainty and pressure as knowledge.
Proven Methods:
- Regular meditation / mindfulness practices (15 mins/day)
- Exercise for cognitive alertness. Ensure ‘Active Recall’ in your preparation.
- Avoid last-minute syllabus additions
- Trust your preparation process, not the noise.
