Step-by-Step Strategy to Prepare for UPSC Prelims 2026

1. Understand the Syllabus and Exam Pattern

The first step is to carefully go through the UPSC syllabus and exam pattern. Many aspirants start studying without knowing what to study. This leads to unnecessary reading and confusion.

Break the syllabus into subjects and create a realistic monthly and weekly plan.

2. Build a Strong Foundation with NCERTs

Start your preparation with NCERT textbooks. These books provide conceptual clarity and help in understanding the basics.

Recommended approach:

• Read one subject at a time
   
• Make short notes
   
• Revise regularly
   

Once the basics are clear, move to standard reference books.
 

3. Cover Current Affairs Daily

Current affairs play a decisive role in the Prelims exam. Questions are increasingly analytical and concept-based, linked with current events.

Daily current affairs routine:

• Read one newspaper (The Hindu or Indian Express)
   
• Note important facts and concepts
   
• Revise weekly and monthly
   

Do not leave current affairs for the last month. That leads to information overload.
 

4. Focus on Concepts, Not Just Facts

UPSC is increasingly asking conceptual and application-based questions.

Examples:

• In Polity, focus on constitutional concepts rather than memorising lists.
   
• In Economy, understand terms like inflation, GDP, fiscal deficit, etc.
   

Conceptual clarity improves accuracy and reduces negative marking.

5. Solve Previous Year Question Papers

Previous year questions are the most reliable source to understand the exam trend.

Benefits:

• Understand question patterns
   
• Identify important topics
   
• Improve elimination techniques
   

Solve at least 10–15 years of Prelims PYQs subject-wise.

6. Join a Prelims Test Series

A good Prelims test series helps you:

• Simulate exam conditions
   
• Improve time management
   
• Identify weak areas
   
• Build confidence
   

Regular testing and analysis are key to clearing Prelims.

7. Revise Multiple Times

Revision is the most important part of Prelims preparation.

Ideal revision cycle:

• First revision: within 7 days
   
• Second revision: within 30 days
   
• Final revision: in the last 2 months before exam
   

Without revision, even well-studied topics can be forgotten.
