... @Jitesh Gajra - I had the same question years ago when I was preparing for CAT. My aim was to get into IIMs.
Every institution has to implement their own process of selecting candidates. Everyone is looking for 'smart' people; but I don't think these exams actually do that. I might be wrong; but a lot of 'smart' people get eliminated in the process.
The only key to cracking competitive exams is to practise previous years papers. Practise them as much you can and you can crack any exam.
I'm inviting @Ramani Aswath sir to share his thoughts.
