I am an alumnus of KIIT. I was a B.Tech Electrical Engineering student. I would first like to tell you how our weekdays looked like. Our classes went on from 10 in the morning to 5 in the evening. After which, we spent some time chatting amongst ourselves in the Kathajodi Campus. The Soc people ended up planning some group activities. Others mostly returned to the hostels.
One thing that I regret is not spending much time in the library. A library is the biggest resource present at any institution. Weekdays are usually filled with other commitments, so make sure to spend some time in the library during the weekends. The library is not meant to just study your curriculum or for lab copywriting. Make sure to do some extra reading. Other than that, try exploring the KIIT campus on foot.
I thought I must offer some advice because I regret not putting in some extra hours for my personality development. You will get numerous other fun tips from people around you at KIIT, but none will tell you to do some extra work for just a few hours during the weekends.
