As a student, I hate the exam system we are now used. This system may be a good way to test a student's memory, and it can tell you nothing about a student's ability. It does not good to students or teachers. As soon as a child begins the school, he enters a world of exams that will decide his future. In fact a good exam system should train a student to think himself, but it now does something like that. So students are encouraged to remember what is taught. The students who comes out first in the exam often may not be the best in their studies. It must be some better way to test a student's true ability except knowledge. And that is where we should do right now.
