I think I still have errors  in all three of my first drafts, but I believe that in Paper 3 is when all the errors were mostly gone. I struggle with the length of sentences and I tend to write a lot more words in one sentences and I thought I did. I would keep typing words and sentences and sometimes its hard to put a period at the end. Spelling and grammar error is also another one of my errors since I tend to type fast and the words would slip away from my finger as I type. But as I go back and re-read my paper I tend to catch them and realize how many grammar errors I was making as well. Finally, in Paper 3 I cut paragraphs down and make new paragraphs that help my paper flow better.
