Will take summer courses raise my high school GPA?

<p>I have maybe a 3.5 right now. I want to raise my GPA to at least a 3.8. Can I take summer courses to do that?</p>

<p>you have to check with the school to see if they approve it</p>

<p>I believe this is technically called a dual enrollment</p>

<p>My GPA for this year is a 4.0. But for previous years it has been lower. The problem is, I’m at a different school this year. Lol. So could my dual enrollment apply to my grades from last year, when I went to a different school?</p>
