<p>Unfortunately some people on this site have to compensate for their lack of intellectual ability by questioning that of others.</p>
<p>Anyway, transfer admission to any top school is VERY difficult. I applied and was rejected to Penn last year (I'm a junior at Williams, if you couldn't tell from my screenname). However, your college GPA is a bit higher than mine. Also, the fact that your GPA is higher than it was in high school and that you were still able to maintain a 3.5 while going through some psychological problems should help your case. I think you should mention your depression, just make it clear that you're over it. You have a good chance, just make sure your recommendations are solid and your transcript stays strong for the year.
Finally, I don't see the point in retaking the SAT II's.</p>
