I cried today, because I failed in the college entrance examinations. Although I haven’t get gotten my grades now yet,

I can feel the bad ending in my heart(You can say "I feel worried" or "I feel like it will be bad") for because I haven’t couldn't finish the tests because lacking of time I ran out of time (or "the time ran out").

I think I studied harder than before in the high school, but the fact is that I failed, I am a loser. College entrance examinations is are a one of the important things in Chinese students’ life, we have struggled nearly 12 years just for the moment we get good grades in college entrance examinations, be admitted to a good university, get a good diploma, and then have qualifications to find a good job.

Above all, no one will look down upon you. Mom said I letted let her down, because everyone who knows me will ask her “how is are your daughter’s grades”,dad recently have has no words with me,he is silent..I really don’t know what should I do. I fail to live up to those who expect me their expectations.

Overall, I can understand your meaning. I corrected the way a natural speaker will say it. Only some errors like when a noun is plural so you have to choose the plural of the verb or adjective. I hope it makes sense. I'm sorry your test did not go well and you feel so much pressure from your parents and society. We all have different abilities and I don't think you are a stupid failure! <3 The time ran out, that's all, if you had more time I am sure you know the answers. So, the test only judged how fast you wrote, not your smartness or how hard you worked. I know it's important and expected of you, but don't let the test make you feel dumb and worthless, you are probably very smart. I can tell by your English! :D
