Mistake on the CommonApp

<p>Hey all, I submitted my Common App to a few schools already, but my sister says I put the wrong scale for GPA. I'm not sure if this is a huge deal since they'll get the guidance counselor reports too, but do you think I should contact the schools and tell them I've made a mistake?</p>

<p>Thanks for your help!</p>

<p>GPA? Yeah I would contact the schools.</p>
