Hello Srishti 

Both the college are very nice on the basis of their academics, infrastructure, placement and faculty. IFIM provides you a very good placement and exposure as many international students are already studying there. 

UPES is also a very good college with a rating of NAAC B . The placements are also good . 

But if you compare both and rate out of 5 

UPES is 3.7

IFIM Is 3.8 

hope it helps :)

All the best :)
