Hi Saurav,
You will have to score very high in CAT, try getting 99.8%ile or more.

Hi Abhishek, even if you have less score in academics you CAT score will be very important because it has 60% weightage in the final selection. So if you get over 96 percentile it will be good.

Dear Rahul,
You will have to give CAT exam, only then you will get to know your chances of getting selected for IIM, Ahemdabad. For clearing CAT, you need to be smart, not knowledgeable, and according to me, Indian Army officers are always more than smart. There were many army officers who joined the army and continued their studies too and retired from higher posts. Solve more and more CAT papers and do give IQ tests (Standford Binet or Culture ), giving IQ tests will help you overcome all your fears.

You must complete your 10+2 and then apply to US universities for engineering. You cannot apply after 10th. Complete your 10+2 with very good academic scores.

As an initial step visit university websites like Harvard, University of Pennsylvania, UCLA, etc. and learn about the undergraduate admission process. Start preparing early on.
