According to some lovers of wisdom, Everything have reasons. So any type of examination we took have reasons. If you are asking what are the reasons of giving those what you called unreasonable exam, you are in the right web page.

Sometimes, examination given to students tries to:

•     make students damn bookish
•     encourage students to cheat, to have a motto of "its better to cheat than to repeat"
•     enhance memorization skill of the students (without comprehension)
•     diminish the objective/mission of education and real world of learning
•     evaluate the learning of students subjectively
