How will my highschool GPA be calculated?

I am a middle school student and my high school English I am taking affects my high school GPA. 1st, 2nd, 4th quarter I got an A (4.0) and 3rd quarter I got an A- (3.7 ish I think). My final grade is an A which would be a 4.0. Will my gpa be my final grade or my quarter grades? Btw my high school uses semesters to grade but since I am still in middle school this class was graded with quarters. If I was graded with semesters I would have As for both semesters.

That’s a question for your counselor. How (and if) HS courses taken in MS impacts a GPA varies by school.

And if you apply to colleges, some have their own recalculation of high school GPA.
