Every topic counted across 67th–71st BPSC Prelims (2022–2026), ranked by how many questions it got. Topics marked BIHAR are Bihar-specific — BPSC returns to these far more often than a general syllabus suggests, and they are the cheapest marks on the paper.

These questions are free to read. The app is the paid part, and it covers the whole exam rather than stopping at Prelims: 83 Prelims topics, 34 Mains topics across 5 papers, the interview, and 19 Bihar-specific topics — 94 chapters in reading order, each with a brief on how the examiner asks it. ₹199 for a month, or ₹499 until your attempt is done — which is the one to take if your exam is close.
