How can a peer review of work be helpful?

I think a peer review is extremely helpful because it can be beneficial to both ourselves and the other students. We get to have constructive criticism on our work to improve where we missed out anything or where we need some clarification on. I have done quite a lot of peer reviews using and realised that I often miss out somethings and have some vague parts which my peer will always point out to me to make my writing clearer. We can also help the others by giving comments for where they might need to improve on. All in all, I think peer reviews are extremely useful to everyone since it'll give us a sense on what we need to improve in our writing.
