Describe previous writing experiences you had (in or out of school) and reflect on what you learned from that experience (not just skills but also habits and ways of thinking about writing) that you can draw on when writing at the college level.
This is a great question. Drawing on the experience of other people is a good way of making your writing better. As I think about my writing in high school, it is pretty depressing. I was a horrible writer. In retrospect, I had three weaknesses.
First, I did not know how to create a strong thesis statement. A strong thesis is key. Without it, you cannot ever have a successful essay. A thesis is what you are trying to prove. And the stronger your evidence is the stronger your thesis is. You should spend a good amount of time on this before you write to make sure that you have a strong thesis statement.
Second, my reasons (body paragraphs) were not very strong. Most of the time this was so because I did not read texts closely enough. One way to make sure that you do not make this mistake is with the use of quotes. If you can select quotes carefully and explain them, you are well on your way to becoming a good writer.
Finally, I lacked confidence. I always thought others were better writers. I wish I took more risks. Taking risks when you are young is great. So, be bold in your interpretations and talk to you teachers about this.
If you learn these three points, you will soar in college. Good writing takes effort, which means lots of rewrites. Start now.
