<p>Two people have asked me to review their essays. I'm not WRITING it for them, just looking over for grammar, idea flow, etc. Is this allowed?</p>
<p>Of course! Suggestions and editing are fine. As long as you don’t actually write it for them, you’re good.</p>
<p>frohawking is correct. Friends are definitely allowed to review and edit essays. Colleges actually encourage applicants to have their essays read by their peers.</p>
