How high can I raise my GPA?

<p>Class of 2010</p>

<p>Currently a junior in high school, and have been concern lately about my overall unweighted GPA. From what I understand my unweighted GPA is a 3.7. Just finish my first marking period and have a 4.0 weighted, 3.67 unweighted ( due to a C in Ap Biology, acutally would have been a C+ in my other classes, and my GPA would look alot better).
Is it possible to raise my unweighted GPA from a 3.7 to a 3.8 by the end of my junior year?
I just finish my first marking period, I have 3 more markingperiods left.</p>

<p>Also, will universities take into consideration of my 2 Ap classes?
-Thanks</p>
