Hello aspirant!

Choice filling consists of all the list of colleges that you can get admission through a particular exam. In choicw filling, you have to arrange the colleges as per your admission desire. You can choose as many colleges in choice filling as you want. All you have to do is arrange them in ranking from top to bottom. For eg, the college in which  you want to take admission the most should be on top and hence in the decreasing priority order. Most of the counselling session involve some kind of registration fees. Please make sure how much. I hope this information was helpful!

I wish you all the very best!
