Yes, I am going through the same problem. With my normal classes, I could finish with a 4.6. However, I am taking many, many outside classes in this one semester (in order to graduate early) and each new one brings my GPA lower and lower. It bothers me, but colleges will understand what happened when they match your transcript to your GPA. Your GPA won’t reflect it, but you will more than likely look better than one who took only the AP classes.
