Hi Friends,

I have given CAT twice in past, and both times, I have flunked badly due to Quant. First time, I could manage only 56%ile and second time, a meagre 67%ile.
This time I am giving CAT for the last time and GMAT for the first time as I consider after this year, I won't be able to start pursuing MBA and will be too late for me. So, I want to give my 100%.

Please advise me about how to prepare for Quant respective to both the exams. I have ample time as the CAT will kick in from Nov onwards and I expect to give my GMAT depending on my preparation (especially considering my prep for Quant).

Thanks! :)
