Figure out what college the DE courses are at, and whether it has a transfer credit articulation agreement with the colleges that she is likely to attend in the future.
If she may be pre-med or pre-law, remember that college courses taken while in high school and grades earned in them do count for medical and law school applications. That would be a boost if she earns A or A+ grades, a drag if she earns B+ or lower grades.
Assuming that these are actually taken as college courses (not the college course syllabus taught in high school format), they may give her a taste of how college courses are run so that it will not be as big of an adjustment when she goes to college after graduating from high school.
