Hello Electta Varghese 

If you are expecting NITs or SPAs with this score then you shouldnot.

To get into NITs ot SPAs you need a rank under 2-3K. so, with 15K rank i dont think you would be able to get any good government college.

As of now even to get a decent college even 5K rank will not be suffiecient. but you can try for some of the private colleges of bengal and punjab.

Hope that helps!
