I maybe did poor in my English writing test

In English Writing Test, I were busy with writing. In tast 2, it need 250 words, but I guess I wrote 400 words. So I did not have time to check it. I worry about that I did not hit the point. Please God bless me. I just need a band 6.

In my English Writing test, I did a lot of writing.  Task 2 asked for 250 words, but I guess I wrote about 400! I didn't allow enough time to check it. Now I am worried that I didn't answer the question clearly.
