That is the real reason he could not get thru..... CAT is basically school level maths which is twisted a bit here and there...so you don't need to start from 2nd year and all that...
The right time to start would be six months in advance and work diligently by solving mocks, analyzing each mock in detail and then peaking on D Day..............
Also, if you don't have the aptitude, you will never get thru......i know guys who have attempted CAT 7 or 8 times and yet have not got thru....you need to be smart and sharp and a dumbo from some call center or a BPO will not get thru...simple!!
Most of the corwd would be engineering crowd with brains and some smart commerce grads with a CA background....IIMs are not meant for any Tom, dick and Harry...........that is the impression that some of these articles purport to create...the tag of elitism does not come easy!! And big 1 lakh plus per month salaries are not meant for the riff raff.....
This is one way of looking at it. The other is that for most exams - like CAT and UPSC we already know the approximate cut off 'percentage'.
For example, for UPSC, almost every year the topper scores 60-65% and the cut off is around 58-60%. For CAT, before the online test, the toppers would generally score 50-55% and getting 45%-48% would earn you an interview call.
So, if you set yourself a target of 50% in CAT or 60% in UPSC you could pretty much be sure that you would get called for interview.
