Engineering v/s Hormones

It's funny to think that WE (yeah... the grand "WE" - me, you , the person in front of you, etc.) are expected to perform our best when our bodies & minds are least prepared to do so. I'm talking about the undergraduates - yup, the one in front of you or even the one you have left behind as your past. The have to deal with the hormonal craziness of a teenager and the emotional upheavals as a result as well as go through the undergrad drill and grill. Not being sure of what they want to do with life doesn't help either. All of us go through this stage and it's a weird feeling but no one seems to remember their experiences!
