So Subjective!

I've discuss with my friend about the exam and feel released a little now, cause we find the standard of scoring is very subjective.

My friend graduated from FLLD in NTU, and studied in a famous graduate school in UK. She've ever taken the job of translator, too.
So, she has excellent English ability, and always get high score in the English written exam.
However, her score in the oral exam is low, even as low as mine.
One of her friend also attended this exam and get high score in this.
According to her description, she almost didn't know the answer about
every question, she just kept saying, "sorry, I'm not sure" or "I have no idea about it'. However, in the end, when she got to leave, she asked to
shake hands with every judges. This action made all judges laughed and said, "it's so diplomatic!" And then, she got the score of89!

My friend and I answered every question seriously, (at lease more serious than thay quy) even so serious to had quarrel with judges.
The scores we got are lower than that guy by almost 20.

There are more examples prove that this exam is very subjective, but I am lazy to write all them down.
I believe I won't attend any exam like this.
It' really wasting time.
The key to win is to cater for the judges's preference, not to express what you've learned.
