Everyday we meet many people's who complain about many things. They act like less human and more like complain box. So You will find many complain boxes in Engineering college. Complaining about system, administration, Attendence and etc.
But apart from their Negativity I think Engineering college life will be one of the best life experience from all perspective.
You will get 4 years to improve your skills, Resources, Support from your parents and the lucky ones with also get support from their girlfriends.
So enjoy this life. Don't make friend to those people's who act like Complain boxes. And enjoy.
