You must take the GMAT or GRE and not CMAT to pursue MBA in USA or any country abroad.

Hi Ayesha, GMAT is not mandatory for alliance school of business , the more you score in GMAT the chances of getting top colleges around the world is getting more, so try to score more than 650. Alliance college of business accept more than 50% in any of the aptitude exam.

The process of getting into IIM with GMAT score is little tricky. You need to work outside India for atleast 18 months and during CAT examination, you should not be in India. If you fulfill these criteria you can apply with GMAT Score.

You should pursue MIM. For MBA, you will need to work for couple of years more. In your scenario, MIM seems to be the perfect fit, with some work experience by your side and a good GMAT/GRE score. It will be easier for you to land at a good b-school.
