Overall gpa along with college admissions.

<p>Hello :), I'm about to be a junior in high school and I have a few questions. During my sophmore year, I had a lot of family problems that interferred with school. I'm usually an a and b student but sophmore year I got b's, c's, and d's. (The d's I'm making up in summer school) which dropped my gpa. Junior year I'm taking ap and honors classes, but is it possible to get my gpa up to a 3.7/4.0 by the end of senior year? Also will this downfall lower my chances of getting into UC's? Will they consider me if they see improvement? I need all the advice I can get. Thanks :)</p>
