I am finding tough to score in Quants , what shall I do in last 14 days? Previous years Question ? or do topic wise questions?

Hi Vidhi Jain, as there are few days remaining, practice qstns from Arithmetic, Algebra and Geometry. Take mocks and sectional tests and focus on picking the easy qstns and solve them correctly.
Revise the basics of all topics (don't leave out the basics of any topic), and avoid silly mistakes while solving the qestions.
