The UPSC Geo-Scientist 2027 exam pattern is divided into three stages: Preliminary Examination, Main Examination and Personality Test. The Preliminary Examination is conducted in objective mode, while the Main Examination consists of descriptive papers related to the candidate’s chosen discipline.
The Preliminary Examination carries 400 marks and consists of two papers. Candidates are required to appear for the papers relevant to the post for which they have applied. Those who qualify the Preliminary stage are called for the Main Examination.
The Main Examination carries 600 marks. Candidates who qualify in the Main Examination are then called for the Personality Test, which carries 200 marks. The final merit list is prepared on the basis of marks obtained in the Main Examination and Personality Test, subject to the prescribed conditions.
The UPSC Geo-Scientist syllabus 2027 varies according to the post and subject selected by the candidate. The Preliminary Examination includes a General Studies and subject-specific paper, with the technical paper covering concepts related to the candidate’s discipline. For Geologists, the syllabus broadly covers areas such as geology, physical geology, structural geology, mineralogy, petrology, palaeontology, stratigraphy, economic geology and applied geology. Candidates appearing for Geophysics and Chemistry posts have to study topics prescribed specifically for those disciplines.
The Main Examination goes deeper into the specialised subject. Candidates should therefore prepare the syllabus according to their particular post instead of following a common syllabus for all Geo-Scientist positions. The detailed UPSC Geo-Scientist Notification 2027 provides the official syllabus and paper-wise examination scheme.
