Q- Apparently you don't really keep much of your high school friends (I probably have 2 TRUE friends). So what's the problem with studying hard, getting into a great uni and making friends there?
In my opinion, due to the fact that high school does classes instead of lectures, you will have more time to interact with the your cohort. You have recess and lunch to chill with your friends...etc. In university, it is a lecture based environment, you might sit next to some awesome guy one day, but due to so much people in the same lecture, you might not get the chance to interact with that person as much. Sure you could try pick him out after lecture or something, but he might have commitments after class anyway. Further mor, a friend you made in high school have a greater bond in my opinion, after all you spent like 5 years with the cohort assuming you never switched schools. Those relationships will be stronger then the 3-5 years you get in Uni. Also, this is the relationships that are most likely pure, not colored by other motives. (I'm not saying ppl u met in Uni have motives but hey, back in year 7 we just friends to play with, now in year 12 I see people sucking up to some friends they rejected before so they could help them....)
I'm thinking about attending O-week to meet some friends before I go to university, should be pretty damn good and it is BYO.
