I've only reviewed a couple of my close friend's personal statements. I usually end up telling them that they should have someone else review it because I am way too biased. One of the essays was really terribly written and was about going into medicine because she broke up with her boyfriend. While any third person would find it ridiculous, I thought the essay represented her really well (she speaks weirdly and I think actually wants to go in to medicine cuz of that breakup). I just couldn't hate it for being way too honest so I referred her to someone else. That person read it and emailed me like WTF is going on with this essay. I was like yea. That essay got torn apart, kinda deserved it though. I stay away from PS reviews now.
