I would like to thank BradK and lannan13 for pointing out the need to define examination. Examination is a formal test of a person's knowledge or proficiency in a subject or skill. I feel that examinations cause stress and worry to students. They may also feel less capable and discouraged if they receive a poor grade. With no examinations, they will have less expectations piled on them. This way, they will be able to be more motivated to study, without the worries of performing badly. Students in countries like Singapore and Japan have many students who are sleep deprived as they study till the wee hours. Lack of sleep is detrimental to a person's health. Also, there is no way to tailor every educational system or examination to meet the learning preference of each student. Surprise tests can be conducted to test a student's knowledge and grasp of the subject instead of a examination where students have to study round the clock to prepare.
