Hello,

It totally depends on you that is if you are allotted a seat in a very reputed college and you are satisfied and you think that there cannot be any improvement after that then you should fill the status retention form. Now for your query the answer is no because you cannot do both at the same time. As in if you fill the form then you cannot appear for later rounds whereas if you do not fill the form the seat is open for all. If it remains vacant till the last round then it is yours or else it can pass onto someone else .

Hope it helps.

Good luck.
