how exactly does GPA work?

Applying to College

<p>my school doesnt give a GPA on report cards they just do it by numbers.. but my average is a 89.3 so what would that convert to GPA wise?</p>

<p>well.. im a junior in high school right now so do you think its realistic for me to increase my average to lets say 91 in just this year? if so what are we looking at in terms of grades for each class?</p>
