Although peer reviews have advantages and disadvantages, in my opinion the good outweighs the bad. While peer reviews may give you fear of other writers' judgment. That fear can also be used to push yourself to apply your all and to not procrastinate when it comes to your deadlines for writing assignments. If you know that you have a peer review coming, then you're going to want to make sure you at least attempted the assignment. Afterall, can a peer review be done if you give them nothing to review? Would you rather look like a slacker with nothing? For myself that answer would be no. I rather give my peer a written rough draft to actually provide me some useful feedback. You just have to remember that your first draft is never your final draft. Peer reviews are a useful tool in writing for both the writers and readers. The point of a peer review is meant to help you, not hurt you. Learn to accept that feedback and embrace it.
