Description: How are school grades determined at different levels of education in your country (e.g., test, quizzes, reports, participation, etc.)? How are grades listed on report cards? In the USA, letters are often used to indicate performance (A, A-, B+, etc.).
Helpful tip: Many students in the US take the SAT and/or the ACT tests as a part of gaining entrance to colleges and universities. Try taking such tests several times so you get a feel for how they are written if the school are considering require such tests.
