I took a peek into AMA website and checked the syllabus of this course.
Those so-called PG courses are bulit on the foundation of UG courses, in other words, they are actually duplicated from UG courses.
As I believe, an normal engineering graduate might have already learnt half of the concepts in those courses, no worry at all. This is just another money-making course, they won't fail unless you have not paid the fee yet.
