UPSC Combined Geo-Scientist Answer Key 2026: Four Paper Keys Released
The Union Public Service Commission (UPSC) has released the answer keys for the CGS(P) Exam 2026 (Combined Geo-Scientist). Four key sheets are out, one each for General Studies (Paper I), Geophysics (Paper II), Geology/Hydrogeology (Paper II) and Chemistry (Paper II). Every sheet gives the key for Series A, B, C and D, with options A to D.
Only the Geology/Hydrogeology paper has a dropped question: 1 of 120, so 119 are taken for scoring. The other three papers score all 120 questions. The key sheets print no release date, objection procedure or portal, so this page sticks to what the sheets show. Download each PDF from Essential Links below.
