I am a Junior in High School. I have seen a lot of discussion regarding GPA and I am not sure what will be its equivalent in terms of CIE (Cambridge International Examinations) A Levels. In CIE there are no marks and only grades are awarded. A* being the highest possible.
In my O Levels (Freshman/Sophomore Years), I took 8 Subjects (Maths, Physics, Chemistry, English, Biology, Urdu, Pakistan Studies and Islamiat. These are the standard 8 subjects in Pakistan and in my school no additional subjects were offered. I got 7 A* and 1 A (In Urdu).
In my A Levels, I am studying Physics, Chemistry, Mathematics, General Paper. I plan to self-study Computer Science and Further Mathematics in my Senior Year.
Would I need to convert my grades to GPA when applying? And, suppose I am able to achieve A* in all of them, what will be my GPA? Also, are APs and A Level Subjects given equal importance?
