Exams can be important

I was going through an article “Are exams so important" posted by my friend Nipun in his blog “Passage To Passion”(http://www.nipunsviews.blogspot.com). The post was on the “Importance of exams”.He wrote that exams were of no use.Rather than describing his topic he focused mainly on the rewards which were given to the winners of a particular exam.
He said that Exams cannot alone evaluate one’s IQ and one’s intelligence.
It is valid.
But I should say that Exams reflect winner’s hardwork and sincerity.
The reply I must give for his view-“Exams are of no use(which is invalid) “ is that exams,as I said above, exams show how one can improve,what one is capable of and what one’s intelligence(which cannot be measured by human intelligence) is upto some extend.
He also said that people now a days are only looking upon toppers and ignoring improvements .Actually they are not ignoring improvers.They only try to appreciate their most successful winners.
He said that byhearting is not a good method.
I am a person who does not like to byheart each and every word given in the syllabus.
It is valid.
What we study must be for ever.It should just not be used to womit in the exam papers.
