BPSC Prelims Exam Analysis at a Glance

The BPSC CCE (Combined Competitive Exam) Preliminary is the first-stage screening test conducted by the Bihar Public Service Commission (BPSC) for entry into Bihar's state civil services. It is a single objective General Studies paper, and the marks scored here decide only who advances to the Mains — Prelims marks are not added to the final merit. This analysis is built from our analysis of 8 BPSC Prelims papers (2018–2025): we parsed every question, tagged it by subject and subtopic, and turned the raw papers into the weightage, trend and subtopic tables below. Treat these as our PYQ-corpus analysis, not as official BPSC data.

BPSC Prelims Exam Pattern

BPSC CCE Prelims is one objective General Studies paper: 150 questions for 150 marks, to be attempted in 2 hours. BPSC CCE Prelims has historically carried no negative marking, but you must confirm this in the current notification. The Prelims is a screening test only — it qualifies you for the Mains and the marks are not carried into the final ranking. Because there is a single paper, every subject competes for the same 150 questions, which is exactly why the weightage map below matters so much.

Subject-Wise Weightage (Our PYQ Analysis)

Here is how the 150 questions split across subjects in our analysis of 8 BPSC Prelims papers (2018–2025). 'Avg share' is the average percentage of the paper a subject claims, 'Total Qs' is the count across all eight years, '2025 count' is how many questions it carried in the latest paper, and 'Range/yr' shows the lightest-to-heaviest year for that subject.

The top three — History (24.3%), Current Affairs (19.9%) and Science (19.3%) — together make up roughly 63% of the paper, so your prep must be anchored here. History alone is nearly a quarter of every paper and is the single highest-yield block. Current Affairs is the second pillar but the most unpredictable, swinging between 13 and 37 questions in a year. Science is a close third and rewards conceptual clarity. After these, Geography (11.4%) is the strongest of the 'second tier', while Polity, Economics, Quantitative Aptitude and General Knowledge are smaller but cheap-to-secure scoring blocks you cannot afford to skip.

Year-on-Year Trends

Averages hide the movement, so here is the year-by-year question count for the six core subjects across our analysis of 8 BPSC Prelims papers (2018–2025), shown for 2020 to 2025. Watch the columns left to right to see which subjects are growing and which are cooling off.

The clearest faller is History: it has slid from 36 questions in 2020 to 29 in 2025 — still the largest subject, but no longer as dominant. The most volatile is Current Affairs, which collapsed to just 13 questions in 2023 before rebounding to 37 in 2024 and settling at 30 in 2025; this is the swing factor that decides borderline results. Quietly, Polity is the steadiest riser, more than doubling from 6 in 2020 to 14 in 2025, while Geography has firmed up to 21 in both 2023 and 2025. Science stays a reliable high-volume subject throughout.

Most-Tested Subtopics

Subject totals only get you so far — the real edge is knowing which subtopics inside each subject repeat. Below are the most-tested subtopics from our analysis of 8 BPSC Prelims papers (2018–2025), with total appearances across all years in brackets.

Difficulty: What to Expect

BPSC Prelims is best read as a breadth test rather than a depth test: most questions are factual and single-concept, so the challenge is coverage and recall, not heavy problem-solving. History is the most scoring block for a prepared candidate because it is large, repetitive and Modern-India-heavy — the patterns recur year after year. Science is similarly rewarding if your NCERT fundamentals in Biology, Chemistry and Physics are solid, since the questions stay conceptual rather than numerical. Polity, Economics and General Knowledge are smaller but among the easiest marks to lock down with standard preparation. The genuine swing factor is Current Affairs: it is both the second-largest block and the most volatile, so candidates who keep a disciplined daily current-affairs habit (with a strong Bihar focus) separate themselves from the pack. Quantitative Aptitude is small and can be partly managed with practice.

Expected Cut-off (Indicative)

BPSC Prelims is only a screening stage, so the cut-off is set wherever it needs to be to shortlist enough candidates for the Mains, and it moves every cycle. As an indicative guide from past trends, the general-category qualifying mark has typically fallen in a broad band of roughly 90–105 out of 150, with reserved categories several marks lower — but this is only a rough orientation, not a target you should anchor to. Because there is a single 150-mark paper, a few extra correct answers can swing you across the line, which is why maximising attempts in the high-weightage subjects matters so much.

How to Use This Analysis in Your Prep

Turn the weightage map into a weekly rotation that mirrors how the marks are actually distributed. Spend the most time on the three pillars, keep the second-tier subjects warm, and use BPSC PYQs as your weekly diagnostic so you are practising the exact patterns the paper repeats.

1. 1Front-load the big three: give History, Current Affairs and Science the largest study blocks each week — they are ~63% of the paper.
2. 2Inside History, prioritise Modern India (125 appearances) and the Bihar freedom-struggle chapters before Medieval and Ancient.
3. 3Build a daily current-affairs habit with a strong Bihar focus — it is the swing factor and the hardest block to cram late.
4. 4Bank the cheap marks: do focused revision of Polity, Economics and General Knowledge, which are small but high-accuracy blocks.
5. 5Solve full BPSC PYQ sets year by year, then review every miss at the subtopic level to see whether your gap is a topic or just careless recall.
