Grading is the process of evaluating a student's performance in school, usually through assignments, tests, and projects. Teachers assign grades, often using letters like A, B, C, and so on, to indicate how well a student has understood the material. These grades help students know where they stand academically and can influence their future opportunities, such as college admissions. In addition to letter grades, some schools use a numerical system, where students receive scores out of 100. This system provides a more detailed view of a student's strengths and weaknesses. Overall, grading is an essential part of the education system, guiding both students and teachers.
