How to Prepare 71st BPSC Exam With a Dual Strategy

The most efficient way to prepare is to study both Prelims and Mains topics in parallel. For instance, if you’re studying Indian Polity for Prelims, extend your preparation with Mains-level analysis and current relevance.

Smart Revision Strategy

  • Notes Making: Use one-liners or bullet notes for quick revisions.
  • Mind Maps: Visual representation helps in linking topics.
  • Weekly Revisions: Dedicate one day per week to revision only.
  • PYQ Integration: Revise with previous year questions in mind.

How to Balance BPSC Prelims and Mains Preparation

To fully grasp how to prepare for the BPSC exam 2025, it’s important to avoid overfocusing on Prelims alone. Allocate 70% of your time to Prelims until the exam. After the Prelims, quickly transition to Mains with at least 3 months of intensive writing and revision.

Use the “Integrate and Isolate” method:

  • Integrate: Study content common to both stages (History, Polity, Economy) together.
  • Isolate: Focus separately on Prelims-only (facts, MCQs) and Mains-only (writing, analysis) parts.

How to Prepare BPSC Exam: Basic Study Material

Choose quality over quantity. Stick to limited resources and revise them multiple times.

BPSC Exam Preparation 2025

Master static GK (History, Polity, Geography, Economy) and practice MCQs under timed conditions. Prioritize Bihar-related questions, take regular mock tests, and revise consistently. 

For Mains, rely on advanced books like Laxmikanth’s Indian Polity, Spectrum’s Modern History, and Ramesh Singh’s Indian Economy. For Bihar-specific content, use Bihar Ek Parichay by P.K. Bharat and the latest Bihar Economic Survey.

Current affairs are crucial for Mains and Interviews but secondary to static GK in Prelims. Focus on Bihar-related news, government schemes, and national events from the last 12-18 months.

Many aspirants neglect Bihar-specific content, underestimate answer writing practice for Mains, or rely too much on coaching notes instead of standard books.
