This can be contradictory to some but I would suggest you to go for KGEC IT course instead of IEM IT. See IEM may show different stats about the placements and student feels it lucrative but in general the average packages aren't that good. So if you draw the case of most probable job type then the package you will recieve in the campus placement of IEM will be lesser than that of KGEC. Also KGEC have really good alumni's and many companies such as Cognizant, Accenture, TCS, WIPRO, Zack Analytics and Research etc visit every year and recruits students with good packages. So if you pursue the course from KGEC not only you will save money, but you will be able to get the job package which will definitely be better than that of IEM.

Now its your choice, but statistically speaking KGEC will be more statistically efficient.
