Hello  P D, 

Your scores are good. Talking about the IIM admission then there are various categories for which they give preference like working experience, good previous year academic records etc. Speaking frankly then its close to impossible to get into IIM AHMEDABAD. But don't loose your heart as you can still get into IIM INDORE, IIM LUCKNOW, IIM KOZHIKKODE etc. But you need to work exceptionally good and must have a percentile of above 97% in CAT. if you have some category like SC/ST or OBC then try to get 89% or above in CAT.

I hope you will find my answer helpful. 

All the best.
