What is the salary for UPSC Geo-Scientist 2027?
The 2027 notification information available for this examination does not state a pay scale, pay level or salary amount. It classifies the advertised positions as Group A or Group B. Do not rely on an unverified salary figure from an older recruitment cycle; check the applicable official service rules for confirmed pay details.
Selection process and examination pattern
| Stage | Format and marks |
|---|---|
| Stage I: Preliminary Examination | Two objective papers on an OMR sheet; 400 marks in total. Paper-I is General Studies (100 marks) and Paper-II is the stream subject (300 marks); each paper lasts two hours. |
| Stage II: Main Examination | Three conventional, descriptive papers of 200 marks each; three hours per paper and 600 marks in total. |
| Stage III: Personality Test | Interview carrying 200 marks; the notice states there is no minimum qualifying mark. |
The Preliminary and Main examination marks both count towards final merit. The notice describes Paper-I as being at science-graduate standard and the subject papers as approximately at M.Sc. standard. There is no practical examination. About six to seven times the vacancies may be shortlisted for the Main Examination, and about twice the vacancies may be called for the Personality Test.
- Negative marking: One-third of the marks assigned to a question is deducted for a wrong answer in the objective papers. A blank answer attracts no penalty.
- Calculators: Not allowed in the objective examination. Non-programmable calculators are permitted for conventional papers.
- Language: Papers are set in English, and Main Examination answers must be written in English.
- Attendance: The notice states that failure to appear in any Main Examination paper results in rejection of candidature.
What conditions can affect or cancel your candidature?
The notice states that failure to appear in any Main Examination paper results in rejection of candidature.
