Answer to the questions.

1. As a writer in high school I was very good at painting a picture of what I was writing about by being very descriptive. Also I was very good at coming up with a thesis statement. I feel as a writer I need to improve on not making some many spelling and grammar mistakes. Also I need to expand on my vocabulary and not use the same word some many times.
2. I expect college writing to be a little bit more difficult because the professor is expecting more from you than a high school teacher would. An example is your professor will expect you to be an expert on what your talking about. Also you will need to use more difficult vocabulary words and not make minor spelling and grammar mistakes. Ideas should come from the writer and his research. My assumptions about college writing come from college students I talked to.
3. Every essay has a introduction, body and conclusion. In the introduction you will find the thesis statement and the background information. In the body of the essay your will find your main ideas. Finally in the conclusion you find the thesis again and a summarize version of your main points.
