First, you join good institute near you like TIME, IMS, Career Launcher, etc. So that you get a better idea of how to solve Questions Papers, Basics, Tricks, etc.
But just joining an institute is not okay.
You have to work hard, keep practising maths problems, logical reasoning, English grammar and all.
As you said, you are in the 2nd year so first, you have to focus on your graduation that is also important, start preparing for CAT in last year or I would advise you to after B.gain 1-2 years of work experience after B.Tech and then go for MBA as it would be better for your admission and placements.
Best of luck.

If you want to go in good B-School then it is must to give the above mentioned examinations.

Hi Sonali,
Not at all, GMAT is basically required for MBA programs. It's not required for each and every Master's degree course abroad.

You don't have any chance of getting admission in a good college. Stanford's cut-off is 740 and Wharton's is 728.
However, if your aim is just to get MBA at any cost then IIPM, Manav Rachna and Manav Bharti are the kind of institutes which exist in the USA who can't provide you placements, but they badly need students so you can search and apply for such B or C category institutes.
