Previous year questions or grand test questions review, which should be given priority?

Revision of whatever u have studied. Not answering something u didn’t study is fine. Not answering something which u have is unpardonable. 1 week is not the time to add data but only to recollect data. U can’t inc u rank NW u can take that in writing… Cuz that’s dependent on what u know till now and not on what u will know… but u can prevent it from falling by revision of ur topics
