Yes, iDAT and iMAT are parts of the IIAD Entrance Exam. However, candidates do not have to appear for both tests. The exam completely depends on the programme chosen by the applicant. For instance, an individual who has opted for B.A. (Hons) Communication Design has to only appear for an iDAT test while an individual who has selected B.A. (Hons) in Fashion Business Management has to sit for the iMAT exam.
