Hi Taylor, your work needs more organize. I mean it is lack of appropriate appearance so thus, unintentionally, can broke reader's interest to read your whole work. Please add a space between your paragraph with each of them providing an answer of each question that the prompt requires.
Looking backward to your prompt
Discuss the subjects in which you excel or have excelled. To what factors do you attribute your success?
In your first paragraph after you say Mathematics and History to be your excel subject, please support your claim on why you excel on them much. Tell us what kind of empirical events or fact that makes them special to you. Moreover, pay attention also about what prompt says. It requires you to state what
factors attribute ..., thus just providing Mr.Zimmerman contribution in following paragraph does not quite enough, you should add more, this becomes important, otherwise you just intend to get mediocre mark.
Hopefully it helps :)
