Here's where you can ask if you have a clear main point or if there are places where you need to provide more details or explanations. Having a reader respond to your writing can keep you from wandering off your point or help you to see where you aren't providing enough information. Before you begin to write, make sure you understand the criteria that will be used to evaluate your work. Show your draft to another person who you know is a careful reader. Ask this person to point to places in your writing that are confusing or unclear.
All successful writers benefit from some sort of feedback.
There you'll find tutors who are carefully trained to help you develop your essay more clearly and more fully. If you'll need to use outside sources, find out which citation form you're supposed to use. Ask to see a sample Works cited, References, or Bibliography page, and make sure your sources are accurate. That way, when your readers are interested in a particular point you're making, they'll be able to know exactly where to go to find further information. Once you've revised your draft, making sure you have a clear focus and all of the necessary information, carefully proofread and edit your writing, checking for errors in spelling, punctuation, and grammar.
