Amity University's MBA is quite low in ranking in comparison to IIMs, FMS, MDI, etc. If you have to prepare for CAT, then it's a better option then to join private universities as MBA. But if you feel you can not crack CAT, then doing MBA from Amity is a good option.

TIME is one of the famous ones in this field.

NSB accepts all test scores. The basic qualification required is graduation in any discipline. In order to know about the CAT percentile and other test percentiles, you will have to talk to our admission officer.

Required percentile for SJMSOM in CAT is 60 percentile and sectional cut off is 53 percentile.
SJMSOM does not consider CET it considers only CAT.

CML- Common Merit List
Common Merit List (CML) is prepared without any relaxed criteria such that the number of candidates in the merit list is equal to the total number of seats available. The aggregate marks scored by the last candidate in the CML will be the CML cut-off score (CCS).

Hello,
You have to be an appearing graduate which is the basic requirement and after that, once the form comes out then you can apply for CAT 2017. At the time of filling CAT form, you can also pick IIMs where you want your score to be send after the results.
Best wishes.
