The elimination of school exams is no big deal.
Back in the days of my high school years, there was a program called “Recommendations”. If you had a C+ average for the year or higher in a subject course, you would be recommended, meaning that you would not have to write a final exam. You only wrote final exams with grades below a C+ average. In summary, final exams are only a summary of questions that you have studied all year long. Why duplicate and waste time?
