Hi Adi Jain,

Thanks for A2A!

ATMA is AIMS Test for Management Admission while MAT is Management Aptitude Test conducted by AIMS. AIMS is All India Management Association. Both the exams are conducted by the same ody and more or less give scope for you to get admission into good B SChools. However, MAT is more widely accepted across B Schools and hence I would prefer going for MAT.
