An English test

We had an English test yesterday. The title of composition was "Online Shopping". Thank God! I have experience with the subject of this article. So you can imagine how happy I was. I put the original write without thinking. Then continue to translate other articles. I thought I was able to get a high score. But I was wrong. Today my teacher said my composition does not meet the requirements. (That's impossible, but it is the true.) I was so excited that did not seriously look at the requirements. It's not the same as what I wrote before. My paper didn't match the requirements. Now I'm worried that I might not pass my English exam. "Joy surfeited turns to sorrow."

Notes:

1. Put a space after every period (full stop) and after every comma. 

2. The test was yesterday, so your verbs should be in the past tense.

3. Most english language publications (except newspapers) use some variation of capitalizing every important word of a title. There is not complete agreement on the rules for capitalization, so you may reasonably choose your own preference. 

4. The sentence I deleted was unclear. My suggested replacement may not be what you meant to say.

5. "my" is a stylisitic choice. You could also use "the" or "this", but "an" is not correct, because it means "some test", but we know which test you are referencing.

6. The last sentence is a proverb. It should be set apart in quotation marks.
