Amending my GPA?

<p>Hi everyone, I made a big mistake and need to know if it's going to be a problem.</p>

<p>I went to the guidance office at my school to ask them what my GPA was, so I could put it on my Common App. Apparently I had a 3.57 Unweighted, so I put that in. Ive already submitted my app to at least one college, but I just realized that that was my GPA for this semester only, not my cumulative one. First, was I supposed to put my Cummulative GPA? Im assuming I was, but if I already did it right, then this isn't an issue. Second, If I was supposed to, is there any way I can notify them that I need to change that detail, or will they notice it once they get my official transcript, or what? Please help if you can, thank you.</p>
