When I was in upper Secondary school, objective test was first introduced into the examination. I simply hate objective test because the answers were all similar. It also means that I must really know the subject well in order to pass. I remember my teacher once said that if you scored 25% in objective test, you actually know nothing!
Statistically, someone found that ticking "B" for every question may even help the student to score high grade. So, one student actually ticked "B" for the 100 questions in 5 minutes and he scored 47%!! He didn't study at all!
So, the next time you didn't study for an exam, try ticking "B" for every question. Ok, do so at your own risk!
