IIM

Yes, certificates of extracurriculars are always an add on. They are really very important, especially in MBA.

Hi Rishabh,
Some of the best colleges from the placement point of view are:
NITIE-Mumbai, FMS-Delhi, JBIMS-Mumbai, IIT-Bombay, and Symbiosis.
All the best.

Well, for IIM A, one should have good curriculum percentage throughout 10+2 and graduation. And, with work experience, you have good chances. Score well in CAT exams at least above 95%.

You need to extremely high in CAT as you will be competing with students who have scored 90+ in all the three 10th, 12th and graduation. You can also work and get those work-ex points before you plan to go for CAT.

At least 95 percentile is needed.

This question is really vague. It is better you do research a bit about the courses and then ask questions related to it.

Hi Aarti,
Getting into IIMS depends a lot on your CAT score, as well as how you do well in interviews and What/GDs. Given your Class X and XII score, I would say you have a decent chance to get into one of the old IIMS, if you do well in CAT. Also, you haven't mentioned your graduation score, which also plays a role in the selection process. Good luck with your preparations and I hope you do well.

For IIM, CAT is must for admission. But, for rest of top B-School, you can give different entrance exams along with CAT like SNAP for Symbiosis University, XAT for XLRI-Jamshedpur, and lots of top B-School also accepts the score of entrance exams like MAT CMAT ATMA. So, choose the college first, and then prepare for entrance exams that accepted by that college.
