Stage 1: Preliminary examination

The Prelims is an objective, multiple-choice test of General Studies. It acts as a screening test – you must score above the cut-off to qualify for the Mains. Questions cover history, geography, polity, economy, science, current affairs and Bihar-specific topics. Speed, accuracy and negative-marking management matter most. Practise with Prelims PYQs.

Stage 2: Main examination
