Can I get into James Madison University, University of Pittsburgh, or the University of Delaware?

<p>I will be going into my senior year of high school next month and I still can't believe it. I have been thinking tirelessly about college since I was a sophomore and now that I'm starting applications, I'm really wondering what my chances are of getting into some of my favorite schools. I have a 4.0 GPA and will have taken 3 AP classes by the end of my senior year (my school doesn't offer many AP classes). I'm interested in being a Biology major as well (I've taken about 5 science classes over 4 years) and being involved in a Pre-Dental program. I'm involved in National Honors Society, National Technical Honors Society, Key Club, HOSA Future Health Professionals (placing Top Ten nationally two years in a row in a dental event and I'm also state officer), and I volunteer at a local hospital. One of the things that I feel is dragging me down is my 1580 SAT score. I've taken it twice so far and have gotten the exact same score. I plan on taking the ACT once and the SAT one more time but that's probably it. What are my chances of getting into these schools? Thanks!</p>
