Can someone read my common app essay and make sure the tenses do not contradict themselves

<p>I'm trying to edit this, but I'm over thinking everything and tripping over myself. I'm usually pretty good at editing, but I'm off right now. Maybe it's the pressure :(( </p>

<p>You're welcome to criticize other aspects as well! Just post in here whether or not you would like to and I'll PM you.</p>
