Sorry your daughters had such a negative experience and the school was clearly so not suited to your needs and expectations - good that you found a way to circumvent that. Homeschooling works for some, and not for others. In the end what matters is that it worked for your children. No one gets to make that call till they're about 50 and they have enough life experience to really evaluate if they were well prepared for the life they would have liked to lead.

You've done your best and can be proud of your efforts, regardless of the outcome.
