Today I got a letter

I know I'm not the best writer in the world, or I don't exactly remember all the rules on punctuation. But today i got a letter from my High School telling me I didn't pass my writing test, again. I first took it in my 9Th grade year. I got a 2 and you need a 3 or higher to pass. And once again I got another 2. What am I doing wrong? I'm doing the format my teacher taught me and I'm trying very hard to pass, but I'm not passing. I never had a hard time with these state tests, but now I have to pass to graduate. My self esteem is going way down. I never thought that I would be one of these people who have to keep on retaking test after test to pass. That's just not me or my family. I feel like I'm letting my parents down, I'm not smart enough to even get a flippin 3 on my writing test. What would happen if I never pass? Would I have to stay in High School forever? I don't think so. I just hope and pray that the 3rd time is the charm.
