who reminds me that my english is not good, and I also treasure every chance that improves my english. I know that my english is so far from what I wish it should be. and I also know that GRE, sometime TOEFL is not easy for majority to handle and more difficult for geting a ideal score. this is why I doubt and argue it. I know it is hard to get such high scores, and I surely believe that if a GRE test taker got a high score, one must has considerable written skills.

sometime, critique is not a bad thing, it can become a stimulus.

any objection is welcome.
