Can I raise my GPA???

Hi,
I am going into my junior year of High School and right now I have a GPA of 3.48, is there any way for me to raise it to a 3.6.

Figure out what went wrong and fix it - study harder, get a tutor, there are plenty of ways to raise your GPA

If your GPA is weighted, take advanced classes

I have a college level class that i am taking this year.
