I believe that Singapore is really a stressful and competitive country when it comes to education systems, but I find that exams is a good way to see if we can understand our teacher's 'lectures'.
I think that our education systems helps our students or scholars to acheive outstanding results in competitions. Exams can help us track how much we understand during lessons.I think that we should not spend too much time on exams but also some time on experiments, as it will help alot when exams questions with experiments. Some students can't answer experiment questions as they are 'straightforward' as they spend time on 'How To Answer Question' and not 'How to Do It'.
