yes they are and placements is also truth of nature,but if you be at these places you will know how the social life in these colleges work.
There are broadly 4 kinds of boys(girls are hard to find) in an engineering college(specifically)-
1.cool dudes-These people are most in numbers,ordinary silent behaviour,talking about games,football,movies and stuff similar to these.Average in studies,listens to teachers and try to obey.Mostly dont drink.
2.Metrosexuals-less in number,wearing 'Levis's',latest haircut and gelled,talk about cars and girls.These people are mainly seen with girls.And some of them may look like "gay" to you,with red shoes and pink kurti.They drink only at fests etc.
3.Rockers-have signature "goti"(beard that Amir wore in DCH) and mostly black T-shirts and canverse shoes,get a haircut twice a year,seen with i-pods or guitars.Seen head banging mostly and couple great with another rare species called rappers(they hide themselves).Drinkers and at rock fest see them near speaker moshing hard.They also enjoy marijuana(weed,ganja) etc.
4.Ghissues-mostly found at first bench,dress formally and sometimes weirdly.Talk only about future MBA,GRE,MS,Projects etc.If you want notes these are the best people to find.Some of them have good impact on girl community.These have hidden talents that show up at fests only.
These people also in some cases harm class unity.
