ABOUT THIS WEBSITE

This website is doveloped for the helping of the aspirants for RAS/RTS exam conducted by the RPSC. This is free website, no charge for any matter. If anybody will find any mistakes or any wrong/disputed matter on this website then please inform me about that matter. That disputed matter will be removed as if requested by you. I am trying to provide more and more useful and important material for the RAS. You can find here everything like Previous papers, Syllabus, Strategy for preparation, Time Table, Forthcoming Exams,Recommended Books for RAS. All matter is not for commercial purpose, is is just for helping the aspirants/students of RAS or/and other same exams conducted by the RPSC.
