About
UPSC Combined Geo-Scientist and Geologist exam ie. UPSC GSI is the National Level Competitive Examination conducted by UPSC under the Indian Govt. The full form of UPSC GSI is the Union Public Service Commission Geological Survey of India exam. The selected candidates work under the Geological Survey of India (GSI) i.e. Ministry of Mines and Central water board (CWB) under the Government of India for Grade ‘A’ and Grade ‘B’ posts.
Latest Notification
The UPSC has released the dates of CGGE 2022. According to the UPSC calendar 2022, the CGGE Stage-I took place on February 20, 2022. Stage II was held on June 25th & 26th, 2022.
