I'm in the process of writing my PS and I came across some online companies that specialize in formulating and critiquing essays. I am a decent writer but I wanted to get some professional help. I was wondering if anyone has used one, and if not how did you guys get help with writing your essays? I found two that I liked (Accepted.com and EssayEdge.com), but they cost a good amount. Are they worth it? Please Help!
