<p>Ah, I understand. If this 91% is the exams, tell me about your normal grades, the ones you get throughout the year on report cards. Keep in mind as well that colleges put less value to PE than to math or English.
As for what I said about difficulty, it’s that in american schools, there are honors classes, AP classes (college level), and IB classes. They are harder than the standard course offerings. Colleges SERIOUSLY care about whether or not you challenged yourself by taking hard classes. I don’t know which classes you took exactly, and it does matter, so that’s why I said it’ll be tough to gauge you without knowing what you took. If you took a lot of advanced classes, especially in math and computer science, you’re in good shape. If you just took a few and most of your classes were non-academic (underwater basket weaving, stuff like that), then chances will take a dive. </p>
