Hello, 

First of all hearty congratulations for getting such a good rank in ecet. Secondly, yes according to previous year cut off's you surely have chances of getting into the college as closing rank for computer science engineering was 6249, for ECE 7167, for EEE 19213, for MEC 15063. However like any other entrance exam, the cut off will depend on the difficulty level of the question paper, number of seats available in the college, and the performance of other applicants. 

Hope this information was helpful.

Good luck!
