Hey bro, congratulations first of all on such a wonderful score. The cutoff last year was around 588 marks for General category. So you come under OBC reservation right, so even the cutoff increases this year, it won't go par 600 for an OBC. So you have almost done it. You have done ur work, ur HARDWORK has paid off, now wait back and relax and wait for the state merit ranks and exact cutoffs to release. 

Once again congrats on ur marks and best wishes for ur future.
