回复：好好复习再考呗。那门差抓那门，平均分上来很容易。你儿子是没有适应SAT考试。注意抓平均分，切忌偏门。

Thank you for response. It was kind of odd that he felt good about the test until he knew the result.  Usually he will have good sense about if he does the test good or not.He has taken PSAT first, we don't know the result yet. I think he wasn't pay much attention to the test.
