Congratulations for cracking KCET!
RNSIT is a highly reputed college and thus sets its cut offs quite high. The usual closing ranks for your category for CSE and ECE are around 7000-8000, as predicted from previous few year's data. So, your chances seem a little less for admission in CSE or ECE in RNSIT.
However you have scored well and you can get many good colleges for your rank, you can use the KCET college predictor to know the colleges you might get :-
