How will 1 bad grade (I got a 79 in A.P. world for 2nd semester of sophmore year) affect admissions into moderately selective schools like Stony Brook, Penn State, and Rutgers? The rest of my grades are OK, a mix of A’s and B’s. Weighted GPA is about a 96 (weighted core GPA is 94.5) and unweighted is about a 90.5 (unweighted core GPA is about 89).
