What a day.

This post is written in English, for fun and as training for my coming English test tomorrow.

I am in the first out of three test season as a high school student. The first test is somehow just a warm up, my school is responsible for the whole test of 8 subjects. Thus the test was easy, it doesn't require so much effort to do the test well. But why can't I do anything perfect on all subject? Even with the subject I am good at I still make some (or may be a lot of) mistake here and there.

The most annoy thing is that I can recognize these mistake quickly after the time is up. I have been in this postion a hundred times, any test I do, I hardly get 100% on any subject.

Does anyone have any ideas what should I do to get rid of this problem, I would approriate any suggest.
