As for me, I think for both examinees and examiners, the examination can show what and how much the examinees have mastered. The results of examinations are just like mirrors for both examiners and examinees. Through examination the examinees can check their work and Become aware of which aspects they have not done well, so that they'll make much improvement in their work. As far as examinees are concerned, they can not only know how they have studied but also find out what they still don't know or what they haven't mastered well. Thus they will be inspired to greater elforts to improve their studying method so as to make greater progress. Of course too many examinations are burdens to both examiners and exami.
In summary, the examination does more good than harm for both examiners and examinees. We must take a positive attitude towards examination. We should take full advantage of it and avoid its disadvantages.
