5 _ Get help writing your personal statement _ No this doesn't mean get someone to write it for you! But getting help writing your statement can be very useful. Others can point out spelling mistakes you may not have seen, or point out how skills you have could be relevant. The very minimum you should do is get a friend / parent / tutor to look over it before you send it off. It could be the difference between acceptance and rejection.
The personal statement is also a great place to explain more serious problems, like less_than_ideal grades or test scores. Don't be afraid to write something like, "I don't test well" in the statement. As long as you can provide a good reason for you app's problems, it's okay to address them directly. You won't be able to hide it from admissions officers anyway, so providing a reason for problems is always preferable to ignoring them.
