GPA's can be tricky to calculate, with weighting certain classes over others. Your GPA is available from your high school, but I sense you don't agree with their calculation. How to Calculate High School GPA? By school policy, the GPA procedures must be established and be in printed forms for students and parents to see. I'd ask for a copy (be prepared to pay a small fee in some schools). I would then use that information to calculate my GPA and see if I got the same results the school had. Mistakes do happen, so you are wise to double-check their math... Even computers sometimes use the wrong information in calculating GPA.
As for calculating your GPA, I believe it uses your end of year grades because those grades come from the average of your marking period. In my high school, we do get our GPAs updated at the end of the semester because that is when we finish the 4 courses we take that particular semester.
