About Union Public Service Commission (UPSC)

The Union Public Service Commission (UPSC) is India's premier central recruiting agency, responsible for conducting examinations for appointments to various civil services and technical posts under the Government of India. The Combined Geo-Scientist Examination is a highly competitive exam conducted annually to recruit eligible candidates for posts such as Geologist, Geophysicist, Chemist, and Scientist 'B' in various departments and ministries. The examination is structured in three stages: Preliminary, Main, and Interview/Personality Test.

The Preliminary Examination serves as a screening test and consists of two papers: Paper I (General Studies) and Paper II (subject-specific: Geophysics, Geology/Hydrogeology, or Chemistry). Each paper contains 120 multiple-choice questions. The answer keys released by UPSC are essential tools for candidates to evaluate their performance and estimate their scores before the official results are declared. The key papers are meticulously prepared and published in a user-friendly PDF format, ensuring accessibility for all aspirants. The release of the UPSC Combined Geo Answer Key 2026 marks a significant step in the recruitment cycle, reinforcing the Commission's commitment to a fair and transparent selection process.

UPSC Combined Geo Key Paper & Objection Window

The UPSC Combined Geo Answer Key 2026 is now available for download as separate PDF files for each paper. Each PDF is structured to cater to the four question-paper series (A, B, C, and D), with each series presented on a distinct page. For instance, the General Studies Paper I answer key PDF contains four pages, with Series A on the first page, Series B on the second, Series C on the third, and Series D on the fourth. This clear segregation helps candidates quickly locate the answers corresponding to their specific question paper.

It is important to note that the answer keys are provisional in nature. UPSC provides candidates with an opportunity to raise objections against any answer they believe to be incorrect. The objection window typically remains open for a specified period after the release of the answer keys. During this time, candidates can submit their challenges online, along with supporting documents and a prescribed fee per question. The Commission then reviews these objections and, if found valid, makes necessary corrections to the final answer key. Candidates are advised to carefully review the answer keys and, if needed, file objections within the stipulated timeframe to ensure their grievances are addressed.
