Hari,

MMMUT is one of the old college and reputed college in UP. Whereas IIIT Kalyani is a new college it doesn't have it's own campus yet and runs in a local college of Kalyani.

If we talk about placements,  IIIT KALYANI first batch passed out in 2018 The highest package was 10 lacs and average 3 lacs.

MMMUT average package is 4-5 lacs and many big companies do vist the campus last ywar DIRECTI offered 27-28 lacs.

But IIIT KALYANI has IIIT brand and it will achieve a good status in future for sure but after 7-8 years.

Now it depends on you what to choose.
