Can you enroll concurrently at the local JC?
Here is an article about transcripts:

Also donnayoung.org is good for transcripts and organizing tools. And it is all free.
Otherwise, I’ve used Learner.org (Annenberg) for many courses, some of which are completely self-contained. Use the drop down menu to pick adult/college courses.
However, I am looking for a good online private school for my oldest. That way, I can keep her out of the public schools, and keep myself out of family court at the same time. My ex doesn't agree with home schooling.
