Hello,

For admission procedure in SASTRA University, it is mandatory to either appear for CAT/ MAT/ XAT/ AIMAT or CMAT scores. On the basis of your percentile( or score) in one of these examinations you will be offered or rejected seat in Sastra University. Hope this helps!

No, Sastra University doesn't accept TANCET scores, it accepts only GMAT, MAT, CAT, MCAT and Sastra Aptitude Test results. So unfortunately you can't apply for the university through your TANCET score. But there are several other colleges where you can apply through TANCET, but again, I can't tell you anything because you haven't mentioned the Sub-specialisation in which you want to do MBA. All the best!
