BPSC Geology Syllabus 2026 forms the foundation for aspirants targeting the optional Geology subject in the Bihar Public Service Commission's Combined Competitive Examination, covering physical, structural, and economic aspects of earth sciences. This optional choice suits candidates with a science background seeking an edge through specialized knowledge. Understanding the syllabus, exam pattern, and preparation strategies ensures effective coverage of high-weightage topics for Prelims, Mains, and Interview stages.
BPSC Geology Syllabus 2026
The BPSC Geology syllabus spans two papers in Mains: Paper 1 (Physical Geology, Geomorphology, Structural Geology, Paleontology) and Paper 2 (Stratigraphy, Mineralogy, Petrology, Economic Geology, Hydrogeology), emphasizing conceptual clarity and diagram-based answers. The exam pattern includes 300 marks per paper (3 hours each), with objective and subjective formats testing analytical skills. Focus on NCERT basics, standard texts like Marland P. Billings, and regular map work for field applications. Practice answer writing to align with BPSC's emphasis on Bihar-specific geological contexts.
BPSC Geology Syllabus
The candidates can go through the BPSC Geology Syllabus mentioned in the table given below for Section I and Section II. The syllabus majorly covers General studies with topics including the Meaning and scope of Geology and its main branches: Social-Cultural Geology, Physical Geology, Archaeological Geology, Linguistic Geology, Applied Geology, Community and Social Institutions, Group and association; culture and civilization; band and tribe, etc.
BPSC Labor Geology Syllabus Section I
The Geology Syllabus is divided into three sections: Section I, Section II, and Section III. Every section is worth 100 points. Sections I and III must be completed. In Section II, candidates may offer either II-a or II-b. Applicants can review the BPSC Geology syllabus from the table given below.
