What is the BPSC Integrated Combined (Aptitude) Test?

The BPSC Integrated Combined examination (commonly referred to as the Aptitude Test for the numbered cycle) is the Preliminary Examination for Bihar Civil Services Group A and B posts. The 70th Combined cycle has 150 MCQ questions on OMR sheets in 120 minutes with no negative marking. It covers General Studies, Hindi Language, Mathematics, and Science. Shortlisted candidates appear in the BPSC Mains (descriptive) and Interview.

What posts are filled through the BPSC Combined cycle?

BPSC Combined cycle fills Bihar Civil Service (BCS), Bihar Police Service (BPS), Bihar Finance Service (BFS), Bihar Education Service (BES), Rural Development Service, Revenue Service, Labour Service, Commercial Tax Service, and several other Group A and B posts in Bihar government. BCS officers become Block Development Officers, SDOs, and eventually District Magistrates. Total vacancies in a combined cycle typically range from 300 to 1000.

What Bihar-specific topics are important for BPSC Combined GS?

Bihar GS covers Magadh Empire and Mauryan period (Chandragupta, Ashoka), Nalanda University history, Champaran Satyagraha (Gandhi's first Civil Disobedience), Sinha Library Patna, Bihar art and culture (Mithila painting, Sonepur Mela), Bihar geography (Gangetic plains, Bihar Sharif, Bodh Gaya, Rajgir), and state government schemes like BSCC, Har Ghar Bijli, Saat Nishchay Part II, and agriculture policies under Bihar model.

How does BPSC Mains differ from the Aptitude Test (Prelims)?

BPSC Mains is a descriptive examination with papers in General Hindi (mandatory qualifying), General Studies I (Indian History & Culture, Indian Geography), General Studies II (Indian Polity, Economy, Science), General Studies III (Bihar-specific paper), and one optional subject. Each paper has 300 marks. Mains tests analytical and writing ability at a much higher depth than the objective Prelims/Aptitude Test. An interview worth 120 marks completes the selection.

What preparation strategy works best for BPSC Combined?

BPSC Combined requires balancing breadth (Prelims) and depth (Mains). For Prelims, focus on Bihar-specific GK (20–25% of paper), standard NCERT-level GS, and Hindi grammar. Since there is no negative marking, attempt all 150 questions. For Mains preparation, choose an optional subject early and study it to post-graduation depth. Candidates with UPSC CSE preparation background transition smoothly to BPSC Mains with additional Bihar-specific study.

Expert Preparation Tips

Prioritise Bihar-specific GS preparation — ancient and modern Bihar history, Bihar geography, tribal areas (Santhal Pargana region), major irrigation projects (Gandak, Kosi), and current economic schemes.

For General Mathematics, revise Data Interpretation (DI) tables, graphs, and charts — DI questions form 15–20% of the Maths section in BPSC combined; also practise Percentage, Profit & Loss, and Time & Work.

Hindi Language is critical for both Prelims and Mains qualifying paper — revise sandhi, samasa, muhavare, lokoktiyan, and practice précis writing in Hindi for Mains preparation parallel to Prelims.

Study NCERT Science from Class VI–X for the General Science section; focus on Biology (human body, health, disease), Physics (electricity, optics, mechanics), and Chemistry (periodic table, acids-bases, everyday chemicals).
