The answer which I am going to give you would be more correct if you had mentioned your category still for instance I am telling by assuming you as a general candidate

You have got a pretty descent rank and you have a lot of options to chose from

Try to look your results in phase 4 Last rank details and you will find many colleges for civil engineering however getting computer science from a top colleges is a bit tough but still there are many good colleges which give computer science at your rank 

Again I will say look at the results and you will get a lot 

Best of luck
