My Freshman year screwed up my GPA. Do i have a chance?

<p>My freshman and sophomore years cumulative GPA is a 4.0 on a 5 scale..I am currently a Junior in high school and I am getting pretty much straight A's. Because of my bad freshman year i am afraid i will not get into the colleges i want to(University of Michigan, University of Virginia, Case Western Reserve, George Washington, William and Mary) please give me advice on how to increase my GPA and/or my chances of getting in these schools. I am also taking 5 AP courses next year</p>
