Never hand in an assignment before reviewing it! First, check the instructions and rubric to make sure you have completed all components or tasks of the assignment. Next, read through the assignment to make sure your ideas make sense, you are not repeating yourself, and you are not leaving out any important information. Proofread for errors in grammar, spelling, and punctuation. Our Writing Guide has resources to help with the writing process, grammar, and more.
Don't rely on the computer to catch errors. While spellcheck and grammar check can be helpful, they do not catch everything. Consider printing your assignment and proofreading a hardcopy as well.
