What are my chances?

<p>I have a total g.p.a of 3.07, which could've been a 3.7 but I messed up my sophmore year of high school. How do I show colleges/universities that I'm a very determined and motivated student and that I will be of great asset to their college/university.</p>

<p>Keep working hard and do really well in the SAT/ACT</p>
