As long as you pull a good GPA, I imagine it shouldn't matter. Keep in mind that one or two B's will hit so much harder if you're only taking 13 credits. If you've been staying on top of classes and are staying on track to graduate, it doesn't seem like it would be a big deal. If you took less than a full course load EVERY semester, then that would be a concern, but it doesn't sound like you're doing that. ADCOMs take course load into consideration, but if you've maintained a 3.7 with a full schedule so far, then I wouldn't worry 🙂
