XAT

See, these all are various entrance exam for either MBA or PGDM the difference is at their toughness and type of colleges offers.
Talking about CAT, this is the exam having highest toughness level but if you scored good percentile, then you will get IIMS and rest will provide B-schools.

Hello Vivek ,
You can give either of CAT, MAT, XAT or you can go for IAT ( IITTM admission test ). They accept either of the scores.
Good Luck!

Since there is not much time left for preparation, you should now go for smart study. You need a study material which focuses on latest topics which can be asked. You can go for Arihant or G.K publications.

Dear Kartik, if you will qualify the CAT exam with good score and eligible for admission in a good college like IIMs, IMT, etc. you will easily get a loan for any nationalized bank no matter what your family income is. Institution will also support you to get this. Do smart labor, qualify, get admission. All the best.

CMAT is better exam among these. As more number of institutes accepts the CMAT score than ATMA and XAT. Also, CMAT is easier than XAT. Few colleges only accept ATMA scores. Competition level is high in XAT.

Hello Prakriti,
As far as I've heard, one can take GMAT as per one's convenience. The CAT notification has been released yesterday, kindly check on their official site. For other exams, there are no notifications as of now especially of SNAP, CMAT and XAT (they are held in Dec-Jan).
