BPSC Previous Year Question Papers PDF (60th to 71st CCE): Prelims Solved Papers & Answer Keys
Complete repository of BPSC Previous Year Question Papers (PYQs) from 60th-62nd to 71st CCE Prelims. Year-wise question papers with official final answer keys, topic-wise question distribution, and repetition trends.
1. Why 30–35% of BPSC Concepts Stem Directly from Previous Year Questions
Analyzing past BPSC question papers is not just revision—it is the single most accurate predictor of the upcoming exam. While current affairs questions change every year, the static core (Modern History of Bihar, NCERT General Science, River Systems, and Indian Constitution) relies on a finite pool of core concepts.
An aspirant who solves and understands all previous questions from the 60th to 71st CCE enters the examination hall with an immediate 35 to 45 mark head-start.
BPSC frequently converts an incorrect option from a 3-year-old question into the direct question of the current exam. Studying all 4 options in every past question multiplies your knowledge fourfold.

3. 10-Year Subject-Wise Question Frequency Evolution
Historical analysis reveals how question distributions have stabilized into predictable patterns:
• Modern History & Bihar: Has consistently delivered 32 to 38 questions in every single paper since 2015.
• General Science: Shifted from simple 1-line definitions in 2018 to multi-statement conceptual physics and biology questions in 2024–2025, but retained its fixed 30-question weightage.
• Current Affairs: Grew from 25 questions in 2018 to 32–35 questions in recent editions, heavily emphasizing Bihar Government scheme allocations and economic surveys.
4. The 3-Step System to Extract Maximum Value from Past Papers
1. Subject-Wise Sorting First: Do not solve full 150-question past papers blindly at the start of your preparation. Instead, solve PYQs subject-by-subject using compilations like Ghatna Chakra right after completing a textbook chapter.
2. Filter Out Outdated Current Affairs: When practicing papers from 2018 or 2020, ignore 5-year-old sports awards or foreign summits and replace those question slots with modern 2026 current affairs questions.
3. Build a "Repeat Triggers" Notebook: Note down dates, treaties, river origins, and chemical names that have appeared more than twice in past papers.
5. Understanding Commission Master Answer Keys & Objections
After every preliminary exam, BPSC releases a Provisional Answer Key and invites candidate objections with documentary evidence from standard government textbooks (NCERT, Government Gazettes, Imtiaz Ahmad).
Typically, 3 to 6 questions undergo modifications or full deletion in the Final Master Answer Key. When practicing past papers, always cross-reference questions with the Commission's Final Corrected Answer Key.
