Read MoreBPSC Prelims Trend Analysis (60–62nd to 71st): Topic-Wise Weightage + Strategy That Actually Works
BPSC Prelims is not random. When you place the last many papers side-by-side and count questions topic-wise (each paper = 150 questions), a stable structure starts showing up. The purpose of this post is simple: use PYQ trend data as an anchor, build a marks-focused ratio of effort, and keep the scope tight so you don’t waste months on low-return areas.
This analysis uses the topic mapping from 60–62nd to 71st and converts it into a practical strategy you can follow regardless of whether the next paper becomes current-affairs heavy or static-heavy.
The 3-Core Engine of BPSC Prelims (The Anchor You Should Never Break)
Across all the exams in the dataset, three blocks consistently dominate the paper:
Current Events + History + General Science together average about 83 questions out of 150 (~55%).
That means if your preparation is not built around these three, you are fighting the exam structure itself. Even when BPSC changes the paper’s “mood,” it rarely breaks this core engine.
Why this matters: You don’t need to study everything equally. You need a plan where your effort ratio matches the paper ratio.
Topic-Wise Weightage Summary (Average + Range + 71st Snapshot)
Here is the cleanest way to read the paper: what is “always big,” what is “swingy,” and what changed in 71st.
| Topic | Average Q (60–71) | Range (Min–Max) | 71st Q | |
|---|---|---|---|---|
| Current Events (National/International/Bihar) | 29.2 | 19–37 | 34 | |
| History (Ancient+Medieval+Modern) | 27.7 | 24–33 | 24 | |
| General Science (Phy+Chem+Bio) | 26.5 | 20–30 | 30 | |
| Bihar Special | 20.3 | 14–26 | 15 | |
| Geography | 14.5 | 10–21 | 12 | |
| Polity | 11.5 | 6–16 | 15 | |
| Economy | 10.4 | 5–18 | 10 | |
| GMA | 9.9 | 9–10 | 10 |
Quick read: Current Affairs, History, and Science remain the heavyweight trio. Geography and Polity act like strong support pillars, while Bihar Special and Economy can swing sharply year-to-year
71st Paper’s Signature Pattern (What It Over-Weighted vs Cut)
The 71st paper is a perfect example of how BPSC can keep the core engine intact but change the internal balance.
71st was clearly CA + Science + Polity heavy, and it reduced Bihar Special and History compared to their long-run average.
- Up in 71st: Current Affairs (34), Science (30), Polity (15)
- Down in 71st: Bihar Special (15), History (24), Geography (12)
Exam meaning: You cannot prepare only “static Bihar + history lists” and hope it works every year. 71st rewarded candidates who had fast, exam-ready coverage of CA + Science + Polity.
The Biggest Structural Change: Post-68 Shift (What BPSC Is Quietly Doing)
If you split the data into two phases—60–67 vs 68–71—a clear shift appears:
- Geography increased from ~12.7 → 16.8 (+4.1 Q)
- Polity increased from ~10.2 → 13.2 (+3.0 Q)
- Science slightly increased (+1.4 Q)
- Bihar Special dropped sharply from ~24.5 → 15.2 (−9.3 Q) ✅ biggest change
Interpretation: Recent papers look more like “standard GS” (Geo/Polity rising), and Bihar-special weightage is no longer the dominating block it used to be. Bihar is still important, but the exam is clearly reducing overdependence on it.
Volatility Check: Which Sections Are “Safe” vs “Risky”
A smart strategy doesn’t just follow averages—it also respects volatility (how much a topic can swing).
- Most stable: History (tight band), GMA (almost fixed at 10)
- Most volatile: Economy (5–18), Current Affairs (19–37), Bihar Special (14–26), Geography (10–21)
What this means in practice:
You prepare stable sections to “lock marks,” and you prepare volatile sections in a way that still works when the paper flips. That is why CA needs daily discipline, and Economy/Bihar need compact, high-yield notes rather than endless reading.
Two Paper Modes You Must Hedge Against
From the same dataset, papers tend to behave in two broad modes:
Mode A: Current-Affairs Heavy
Examples include papers where CA shoots up (e.g., 66th/70th/71st patterns). Here, the exam compresses static space and rewards speed + breadth + recent updates.
Mode B: Static-Heavy
A classic example is 70th Re-exam, where History + Geography surged while CA fell sharply. Here, depth in static and PYQ-style traps becomes the differentiator.
Your preparation must survive both modes. The only way to do that is: keep the anchor trio strong, and build Geo/Polity baseline (post-68 trend), while keeping Bihar/Economy compact but complete.
Strategy Blueprint (4A Framework): Assess → Align → Act → Audit
1) Assess (Understand the paper’s real ratio)
The paper repeatedly tells you: CA + History + Science ≈ 55%. If your schedule treats these as “just another subject,” you’re misaligned from day one.
2) Align (Match your study ratio to question ratio)
A safe time split that matches both average weightage and recent shifts looks like this:
- Current Affairs: ~25% (because it can spike to 35+ Q)
- General Science: ~20%
- History (A+M+Mo): ~18–20%
- Geography: ~10–12% (post-68 rising)
- Polity: ~10–12% (post-68 rising + 71st spike)
- Bihar Special: ~8–10% (reduced but still present)
- Economy: ~6–8% (volatile—prepare smart)
- GMA: ~4–5% (steady practice, low time)
This ratio prevents overinvestment in Bihar-only preparation and protects you if the paper turns CA-heavy.
3) Act (What to do inside each block)
Current Affairs: Build daily coverage + weekly consolidation. Don’t keep it as “news reading”; convert it into MCQ-ready one-liners with context. Include Bihar-specific CA as a separate sub-file so it doesn’t get lost.
General Science: Treat it like a scoring bank: revise core concepts and PYQ patterns, and ensure you’re strong in common traps (units, properties, basic biology facts, everyday science).
History: Don’t read it as a story. Read it as a question-generator: timelines, matching, institutions, key terms, and “which is NOT correct” style statements. Your goal is quick elimination power.
Geography + Polity: These two are your post-68 growth assets. Build a clean static base, revise frequently, and practice conceptual MCQs rather than only memorizing definitions.
Bihar Special: Prepare it as high-yield capsules—history, geography, polity, schemes, culture—because its share has dropped, but it still decides cutoffs when asked.
Economy: Because it swings, prepare it in a compact “exam sheet” style: basic concepts + key terms + budget/economic survey themes + common MCQ traps.
GMA: Don’t overstudy; practice consistently. It’s stable and time-efficient if you maintain rhythm.
4) Audit (Mocks + PYQ loops)
Your preparation becomes real only after 3 loops:
- Topic-wise PYQ practice
- Full-length mocks
- Error-book revision (wrong answers notebook)
This “audit loop” is what converts knowledge into marks.
Verdict: The Most Trend-Proof BPSC Strategy
If you want a strategy that survives paper mood changes, your safest formula is:
Anchor: CA + Science + History
Upgrade (post-68): Geography + Polity
Compact but complete: Bihar Special + Economy
Maintain: GMA practice rhythm
That combination matches the data, respects volatility, and protects you from both CA-heavy and static-heavy papers.
FAQ
What is the most important section in BPSC Prelims based on PYQs?
Current Affairs is the biggest single block on average and can spike heavily, so it needs daily preparation.

Which topics increased after 68th BPSC?
Geography and Polity show the strongest rise in average questions in the recent phase.
How should I allocate time for BPSC Prelims?
Allocate the highest time to Current Affairs, Science, and History, then strengthen Geography and Polity, with compact revision for Bihar and Economy.
