How to calculate your GPA when...

<p>How to calculate your GPA when your country's educational system differs considerably from the American one? For example, we do not have the credit hours system, and you take classes in different amount of hours throughout different semesters. Should I calculate the average or what? (for example, take history, I have two a week the first and the second years of high school, the third, final I'm gonna have 8. So should I take 4 as the credit,or calculate GPA for each year?).
Also, does GPA consist of ALL courses grades you have? This year I'm taking 14 or 15 classes, so do I calculate my GPA from them ALL? Unlike in the US we can't choose classes, all of them are obligatory, so I have subjects I'm not good at, on which grades I'll have in all my papers, but they are completely irrelevant to my subject of study in college. Or maybe should I take 6-7 subjects that are related to my future major?
Is GPA even needed for international students?
Help me out because I feel a bit lost in all that international students application (I still have some time though so please don't get annoyed with how little I know :)</p>

<p>If your school does not calculate GPA, you do not have to report it. If you still want to report it, you probably should calculate the average grade of all of the grades you have. The best way to know what is the best thing to do, however, is to contact the colleges you are going to apply to.</p>

<p>I didn’t put GPA down as I’m a British Student with GCSEs/A-levels. Don’t bother if you won’t get the equivalence exact.</p>

<p>there are actually places that will calculate your gpa for you (for a fee, of course), but its not necessary. and some schools only consider core subjects, or subjects related to your major, so 15 subjects may be reduced to like 5 or 6. even if its not going to be used for gpa evaluation, a C or D doesn’t look that good on your transcript, so try to keep your grades up regardless.</p>
