XAT

First of all decide which institute and which specialisation you want. After that, look for the exams such as MAT, XAT, CAT, CMAT, ATMA, CET, NMAT, etc. and see which all exams, institute will accept for admissions and prepare accordingly.

Hi,
XAT takes applicants for Xavier's institutes across India.
SNAP for Symbiosis, NMAT for all three NMIMs across India. Although XAT score is also accepted in other colleges, you can say it's better to appear for XAT along with the others to be on safe side.

Hello Deepak,
XAT is a more challenging exam as compared to MAT, and requires a lot of focus and dedicated preparation to clear it with a very good score. Also, a lot of reputed B-schools like XLRI, SP Jain, etc. accept XAT scores, thus making it more important than MAT.

No, you need to take the test again.

KJ Somaiya Institute is best for PGDM and MBA in Mumbai and cut off is approximately 99% in CAT.

Hi,
This cant be predicted. As know your score or percentile, you need to know:
1) Total no of candidate can appearing in the exam .
2) Number of candidates who have scored less marks than you.
Both are unknown to you so you have not calculate it.Because this information is hidden to candidate.
If you collect above two date, then you can easily calculate your percentile.
