10.Do you find examination helpful to your studies?Please gi

There are many arguments about examination.Some people think examination is the only way to test how well the students have mastered the knowledge .But on the other hand ,some people think examination can't test what the students have really studied .As for me ,I think the result of the exam is just like a mirror,Through examination,teachers can know well about what students have mastered and what they haven't.As for the students,they can check their study.Examination can also inspire the students to improve their studying methods and to work exams will be burdens for both teacher and students
