So I come from Indonesia and our government has its own curriculum and by the time we graduated high school we will receive a high school diploma called 'Ijazah SMA'. However, I attended a private international school that uses the Cambridge University A Levels curriculum. So I currently have an A Level certificate with 3 subject passes which I got after completing Grade 12 and is accepted for entry into American universities. I asked Britsimon this question but he was unsure of the exact action an individual CO will do. Does anyone have any experience using foreign high school diplomas in a country?
