Hello Srijita

As this system is implemented first time so it can not be predicted exactly that what will be the cut offs.

And also the cut offs will depend upon April exam and other various conditions. So you have to wait till April exam results.

But try to secure atleast 80+ percentile for qualifying ( may vary as I said; it will depend upon various factors).

But to secure a good college you have to secure a good rank and for this percentile should be 95+ .

So good luck
