Transferring LAC to UPenn

<p>Hi
I'm freshman in Liberal Arts School called Knox and I always wanted to go UPenn.I know it's not easy, but just wanna try it.<br>
My HS GPA is 3.7 and had a decent extracurricular activities - but not extraordinary impact things. And received some academic excellence awards from HS. I got 27 in ACT and willing to take it again after a year and I'm pretty sure I could get above 30. Do I have any chance to get in to UPenn? Or... other ivy schools also.<br>
Plus, could you recommend other prestige schools that I could possibly get into? (And has good natural science faculties and pre-med stuffs)<br>
Oh and I'm an international student. No green card. Thank you all :)
*and please assume that I'll got straight A on my freshman year.</p>
