Reflect upon

In my opinions my papers are good and when I write about a topic that I know alot about I write very well. when it comes to writing a paper talking about the meaning of something like life or going for or against a topic such as gay couples adopting, this is when i do my best. I actually thought I was an excellent writer but that was in high school. Now I have entered college and I need to expand my vocabulary in order to write better papers.I need to learn where to put commas and periods and where not to put them. I also need to be more careful when I am writing and reread my paper to see if the sentences make sense.
