Heyy Anuj....

IET is very good option in comparison AKG . Main benefit is in fees as the IET Lucknow is goverment college while AKG is private. For the  placement AKG is good for CS/IT branch mainly but in IET alsoalso  companies also come and placement is good. And if you want to crack GATE then IET is best as you'll get ample amount of time for your preparation.
