If you've finished your draft after working on it for hours, and you don't have time to take a break before proofreading it, what is
the next best option?
Rest assured that your spell check and grammar check have caught the most important errors in your paper.
Skip proofreading. The most important work is done anyway.
Push through and proofread it yourself.
Ask a classmate or friend to proofread it for you. It's important to have a pair of fresh eyes to look for errors.
