Dear,

You will have to pay for the college and course allotted to you within the time given, otherwise you will lose your allotment along with all the existing options in the stream to which the seat allotment belongs.You need to do a fee payment to confirm the seat.A fee receipt will be issued by the bank or can be printed from the online payment page as token of allotment.As you have been allotted seat, you should take admission to the college allotted. Those who will not take admission will lose their allotment along with the existing options in the course to which the allotment belongs. It is also important to know that options once lost will not be available in the subsequent phases.

You can also wait till the second round by changing your options to get a better college if you want.

Hope this helps!
