UPSC Geo Scientist Syllabus 2026 (Out): Check Prelims & Mains Syllabus
UPSC has given a detailed UPSC Geo Scientist syllabus 2026 for both the Prelims and Mains exams. This syllabus covers posts that include Geology/Hydrogeology, Geophysics and Chemistry. Prelims consist of two objective papers- Paper 1 (common, graduation-level science) and Paper 2 (stream-specific, M.Sc. level). Mains has three compulsory descriptive papers for each stream, all at the M.Sc. level.
UPSC Geo Scientist 2026 Prelims Syllabus
UPSC Geo Scientist 2026 Prelims has two papers. Paper 1 is General studies and is common for all the three streams.
