What is the RPSC RAS exam?
RPSC RAS is the Rajasthan Public Service Commission's flagship recruitment exam — formally the Rajasthan State and Subordinate Services Combined Competitive Examination (RAS/RTS) — conducted from Ajmer. Through one common exam it fills gazetted and non-gazetted posts across the state administration, including the Rajasthan Administrative Service (RAS), the Rajasthan Police Service (RPS), the Rajasthan Accounts Service and allied services such as Tehsildar and Block Development Officer. For a graduate in Rajasthan, clearing RAS is the surest route to a career as a Deputy Collector, DySP or equivalent officer.
The selection has three stages: a Preliminary Examination, a Main Examination and an Interview. The Prelims is a single objective General Knowledge and General Science paper of 200 marks that acts only as a screening test; the Mains is a descriptive written examination; and the final Personality Test and Interview decides the merit list together with the Mains. Because the Prelims carries one-third negative marking and a very wide syllabus, accuracy and broad, well-revised knowledge — especially of Rajasthan — decide who moves on to the Mains.
