Hello Aspirant, 

After registering for admission you first have to upload the required documents. At the time of 1st round of counselling you have to first fill the choices for the colleges you want admission in a preference order. And after the results for the round if you were selected in any of the choices you will get a Allotment letter. And this procedure happens for all the 3 rounds. And then you have to submit the Rs. 40,000 of fees, and at the end you have to visit the college for fees submission 

Hope this helps
