may i suggest getting to know her better as a normal classmate
before deciding on whether you wanna move in on her.
just because someone may be a hot chick it doesnt mean that she has
a good personality... or is someone you might enjoy spending you
time and effort on.
do research on her (friendster, classmates, rumors, etc)... try to
interact with her... get to know what kind of people she hangs
around and make sure you leave some sort of an impression on
her.
never attack too early
