Query:

The main query is I wanted to know that will preparation for IAS help me in RAS Examination or will i have to prepare in a different manner for RAS totally?

Answer:

Dear Candidate,
IAS examination preparation helps in state civil services exam. The syllabus of IAS exam and state civil service exam is almost same. If you are preparing for RAS exam then you have to prepare exam with different approach. You have to know about history, art, culture, geography of Rajsthan,Specially. The exam pattern of RAS & IAS is also same. So you don't need to worried about that. you should concentrate on your preparation.

All the Best
