hiii this is my first post

because i need help!! lol. i got accepted in spring 2008 (very happy since berkeley is my #1 choice) and i REALLY want to do the fall extension program. and almost everyone is telling me to do it, including a junior from cal and my friend who was in the program last year....and my sister who is a senior at cal. the only thing that is stopping me is my dad. he is not letting me because of the cost...and i dont know what to do! i REALLY do not want to attend a community college...im actually kind of scared of going to berkeley in spring not knowing anyone while everyone already knows each other. and also the transition is scaring me (my sister already transferred from sac city to berkeley after 2 years and so my dad said "your sister is graduating this year so youll be fine....ugh.) i told him i was going to try to get a job in the summer and he said ...even so, i would not be able to cover the costs. and that i should think of them more than myself. we didnt get any financial aid which suuucks because we're under average....but, oh well.
i would really love to attend the program. i was...kind of sad that i didnt get in fall. but this has made me..ahh! over the top!!
what do i doooooo!! someone help! lol
