What is the BPSC Exam Pattern?

The BPSC exam pattern is divided into three stages — the Preliminary Examination, the Mains Examination, and the Personality Test (Interview). These three stages are conducted by the Bihar Public Service Commission to recruit candidates for various Group A and Group B posts in the Bihar state government. Understanding the BPSC exam pattern stage by stage is essential if you want to plan your preparation effectively.

BPSC Exam Pattern — Stage 1: Preliminary Examination

The first stage of the BPSC exam pattern is the Preliminary Examination. It is an objective-type (MCQ) paper designed to screen candidates for the Mains. There is only one paper in this stage, covering General Studies.

Since there is no negative marking in this stage of the BPSC exam pattern, you should attempt every single question — even an educated guess is better than leaving a question blank.
