I wish that our school gave some credit for pre-AP/honors/dual enrollment courses. Thus far, dd has taken and gottens As in every pre-AP class available save for one that she chose to not take at the pre-AP level b/c she didn't like the subject that well and because she already had two other pre-APs plus multiple science classes that year (she did get an A in the regular class, though). The pre-APs easily have double the work of the regular level class and cover a lot more material, but there is no GPA bonus for taking them.

She has her first dual enrollment class next year along with some APs. The APs will give that +.02 bonus, but the dual enrollment, like pre-AP, has no GPA bonus either. She is, none the less, probably going to take physics as a dual enrollment her senior year rather than as AP because she'd have to take two science classes again next year to get the pre-AP physics in first before getting to AP. Her school really is not willing to flex on that for anyone.
