NOTE: If this is a case for everyone, I doubt the timely conduct of Rajyaseva Prelims on 7th Apr 2013. Considering all technical issues with the application process etc., and other scheduled exams like banking, UPSC, etc.; Rajyaseva Prelims exam may get delayed by at least 1 month. This is just my personal opinion so be ready for anything!
