Hi aspirant,

To join the college inside Tamil nadu,it is mandatory to attend TANCET exam for MBA.But the cut-off varies for tier 1,tier 2 and tier 3 colleges.

You can also appear for CAT or MAT  or XAT exam to get into MBA in any college as per your wish.The only criteria is that you should meet the cut off set by the respective college.

All the best!
