Personal Statement and application editors/services?

Hello, has anyone here ever tried any of those dental school application help services such as predenting.com, accepted.com, or dentalschoolcoach.com? Since my GPA is low, I want to make sure everything on my application is as good as possible to help boost my chances of getting into dental school.
