What sort of things can I do to improve my chances of getting into Cornell?

<p>Hello! This is my first post here. Cornell is my dream school, and although it is highly unlikely that I can get in, I will do ANYTHING in order to. </p>

<p>Here are some major issues:
I had some health issues freshman year, causing a very low GPA. -- Can I explain this in my application?
Sophomore year, I went to an online school first semester (sort of a transition period before boarding school), how bad does that look? Second semester I went to a boarding school, because I thought that would be a better school for me, turned out it didn't. For junior year I went back to my original public school. (this is clearly quite weird).
I have absolutely no extracurricular - what would be the best ones to start?</p>

<p>I am interested in per-veterinary science - most likely biological sciences as a major.</p>

<p>I take straight honors classes, with approximately 12 AP classes by the end of high school</p>
