exam..

can anyone tell me what's the meaning of exam??
isn't very important for a student??
what could we learnt through exam??

exam = a formal test of knowledge.
actually it's really important for a student in study life..it can show others directly your level..your standard without saying a word.
but nowadays, many students try their hard to study to get a good result even study till midnight..whole day..make their healthy down.
they should study for their future n not for passing papers.
for me..i learnt a lot of things through exam such as how to manage my time..maintain my healthy..relax when i stressed..n the most important is enjoy my life...so appreciate exam make me learnt lot of things..
i hope all of you can treat exam purposely like me...dont misunderstand it!!!
