Hi,

Your rank is pretty good. You can expect a seat in IPU. But right now, it cannot be predicted whether it will be a government college or a private college. You may use this link to check specifically about the colleges:https://www.careers360.com/college-predictor. 

Now, the admission procedure goes as follows: 

If your rank is available in cut offs/merit list, then you will have to attend counseling. If in any case you miss the counseling, the seat will be given to next rank holders. The counseling can be offline or through online mode. Next, you'll have to take all your documents at the time of counseling and you'll be alloted a college as per your rank. Then you'll have to pay the fee and complete all the formalities and then finally your admission will be done.  For all this procedure, do keep yourself updated with the notifications from the official website of IPU.

Hope this helps, good luck!
