This was my first book by Chetan Bhagat and must say I read a couple more of his books because of this one. Chetan Bhagat does clear it out in the initial pages itself that this book doesn't give any tips for IIT wannabees. Far from it, it's how NOT to behave when you get in there. There isn't anything specific about IIT. Anyone who has gone through rigorous education course at any reputable institute can easily connect. It is the tale of 3 pals, the ups and downs in their friendship, their efforts to 'survive' at the IIT and get out with a decent job offer in hand. If you are looking for some serious literary content, you may not find it enough in this, although there are some serious moments articulated delicately.
It's lighthearted, comical read. I'll read it again in a few months time and I'm sure I'll enjoy it just as much. All in all, it's the best of what I've read from Chetan Bhagat.
