How much will my GPA Raise?

<p>currently i have a 2.5 and im a high school junior. I have good grades this year and is also retaking the classes i flunked last year online. I have to retake Geometry and Spanish, yet I'm taking
Spanish 1(2 semesters)
Geometry(1 semester)
French 1(1 Semester)
AP Psych (1 Semester)
Algebra 2 (1 semester)
Journalism (1 semester). I have A's and B's in them so far.
How much will these classes raise my GPA?
Btw I took US History and Science online already with my grades being an A & B.
So I took 7 classes online with A's and B's. Will that help raise my GPA to at least a 3.0? I'm also taking chemistry this summer as an extra class. So I guess I'm taking 9 classes. How much will that help my GPA?
I REALLY want to go to the University Hawaii at Manoa and their MINIMUM GPA is a 2.8. I want at least a 3.0. I also have over 40 hours of community service. </p>

<p>Maybe use an online GPA calculator, otherwise it’s really hard to say.</p>
