Good maen!
Our grades go from 1 (the worst) to 10, the best. Finals at most universities are approved (pass) with 4, but the partial (mid-semester, I guess, or something like that. There are exams that cover around half of the course, while the finals cover the entire course) passing grades are decided for each course's main teacher. For example, in our course, the passing grade is 5. If you don't pass, you have another chance (another exam) and if you don't pass, well, you did not pass. Traditionally, some courses have "promotion system", so if a student approve the two partials with some good grades, perhaps 6, and a good average, that could be 6, 6.5, 7, they don't have to go to the finals. They pass. We use to do that, but since pandemics we don't do promotions, because we are not 100% they don't copy each other in the partials.
