I believe that children who need off-campus training courses are only trained because their learning ability is not strong or they need to improve their ability. If they are very capable and don't need to come to an off-campus training class at all, then this kind of elective examination has no meaning at all, which can only make them feel insecure and dampen their confidence.
See the purpose. I think it depends on the ultimate goal of this selection exam. If the ultimate goal of this selection exam is to select a child with strong ability, then I don't think it makes any sense. If this selection test only depends on the level of each student, then I still support it, because we need to know how strong the child's ability is before we can teach students in accordance with their aptitude.
Generally speaking, therefore, the most important thing is to see what the purpose of this training course is. If the purpose of this training course is to see how strong the child's ability is, then I think this exam is quite good. I also support this exam, so that children can know where their shortcomings are, and then train in a targeted way to strengthen their abilities.
