goin sec 1 next yr ?
pick some people you seem to like, or seem nice, make friends, then
ask for their contacts, so if have anything dont know can call and
ask and help one another ....
conversation wise, talk bout anything since you all are still
strangers to one another. There sure have alot of things to talk.
Talk to all diff kinds of people (other class also can), hall,
canteen, toilet, male, female, whatever .... then slowly you'll
know who you can click better with 
sec school is fun, enjoy !
