求高手指点. 我知道漏洞很多，不过我是真心想学英语。 希望有人能帮忙，在下不胜感激。

我改了下，你可以参考。

The second practice test has finished, there is a fifty grades' gap between my grades and the lowest criterion of examination of the frist-class university. The big gap lets me feel frightened. I remember that once I said "either went to the frist-class university, or went to die. ". Now, should I wake up in someway? In the following days, I will try my best to study and achieve my goal. Nothing is impossible, I will use my sweat and blood to write my honor.
