Hello, 

As your rank is 3k+ so basically if you are from Gen category you have less chances to get your seat in college. If from any other category, it will depends on no of seats reserved in that category, so chances for a seat varies according to that.

You can opt for counseling depending on seat to student ratio and which stream or course you are Choosing, cut off will vary. You might get a seat depending on thr cut off. after the counseling those who have cleared the cut off and eligibility criteria ,they will be alloted college based on their rank.
