Hmm...I guess it's technically overall...but they usually hope that your pre-req gpa is higher than your overall gpa. Even though it's not always the case. 😛 You should probably call the schools you're most interested in and ask how they treat gpa. Sometimes they weigh it very heavily and some weigh the OAT more heavily. I was told by one school that there is a cutoff, but it's not a hard and fast rule. If you are exemplary in every other aspect, they may be okay with a little bit of a lower gpa. Don't hold me to that though, talk to the schools. 😛
