Dear aspirant
First of all you can choose as much choice you want. you can evenchoose all the choices offered to you . Now we discuss about the rule for choice filling of more than one round .
suppose you have selected total of 100 of choices in rhe choice filling and you sorted them according to your interest from 1 to 100 . Suppose you are being allotted 35 th no choice . Then 2 things can happen . If you are happy with your 35th option and you don't upgrade then you have no choice left other than 35 . you either get admission in that try for next year . But if you upgrade then in the counselling if any of the above 34 choice's seat becomes vacant then you get and if not then the previous 35th nunber choice becomes your only option. But under any circumstances you can't get the receding 65 choices after the 35 th number . The same thing happens in every round.
And one thing  the candidate whose rank is better he or she choose to get first available seats.  So 535 marks candidate get to choose first than 500 one.
So choice feeling and sorting is very important.
hope this helps.
