Does she have a small list of the public universities she hopes to attend? If so, I would check with them and see what would transfer. For my daughter we did this and found she could get several credits with her DE/College Credit Plus courses. She then chose courses for her senior year that would transfer against required general ed courses. (We emailed two colleges junior year with a short description of the courses to see what would transfer.) As a current college sophomore she is taking junior level courses and could graduate early if she chooses.
For my son, now a high school senior, he has a few DE courses but more AP courses. He wasn’t as sure of his top schools junior year like my daughter was so for him he chose to go the AP route. He found more of his group went the AP route. In researching his top few college choices now, it will be interesting to see how it plays out. Some allow AP credit without DE, another both AP and DE, while another gives credit but not towards any requirements.
If your daughter is interested in the DE courses, and they will cover college requirements, it may be worth the cost. Good luck to her!
