Hi RadheyaKulkarni,
From what you're asking about, it's not clear if you're thinking about "cramming" during this last day or two during the Exam (since that type of approach rarely leads to great results with Tests such as the GMAT, since you might end up inadvertently burning-out before Test Day). Some general practice and light review (NO CATs and again, NO 'cramming') would be fine - and if you're scoring at a reasonably high level right now, then you would be better served by getting some extra rest so that you can go into Test Day calm, clear-headed and ready to work.
GMAT assassins aren't born, they're made,
