Good for her on putting them in her rearview mirror.
Homeschool or GED.
Nothing really wrong with GED. I have been to the GED graduations & they get their diploma just like anyone else. Come to think of it...in all my working days, nobody ever asked to see my high school diploma. They may ask if you graduate; don’t know if it is ever actually checked out. I DID graduate, but could I prove it? As I can’t find my diploma any more....that was “a long time ago” as Waylon Jennings says in one of his songs.
