In satit thepsatri school, they try to make sure every student achieves the desired abilities of the curriculum. They conduct evaluations in the form of giving questions at the end of each meeting. They make sure all students can do the desired activities well and in accordance with the rules. I have seen teachers who give extra classes outside school hours to students who are done outside of school. Schools provide one day for sports where on that day students will only do sports activities that have been determined by the school.
