Step-by-Step Preparation Roadmap
1
Understand the Syllabus & Pattern

Download the official 2026 notification and map every topic in the syllabus. Identify your weak areas using a diagnostic test before you start studying.

2
Build Subject-Wise Foundations

Spend the first 30 days on concepts — especially Reasoning and Quant. Use standard textbooks and solve chapter-end exercises, not just shortcuts.

3
Current Affairs & General Awareness

Read a quality monthly GK digest and follow PIB / important government schemes. Cover at least 3 months of current affairs before your exam date.

4
Mock Test Routine

Attempt at least 2 full-length mock tests per week after your foundation phase. Analyse every mistake — why you got it wrong matters more than the score.

5
Revision & Speed Building

In the final 4 weeks, solve previous year papers from the past 5 years. Focus on speed — SSC Tier 1 allows only 36 seconds per question.
