I started doing the previous years' CAT Papers 1990-2008 few months back, then left it halfway realizing that the fact the those papers were more of time based tests.
Then two days back while reading reviews of this year's paper, i read in one review saying that almost 33% questions were from previous CATs!!
With 10 days left, should i start doing those papers again? Atleast browse over all the questions?
Or continue giving tests and revise. (Which i am currently doing) 😐😐
