B.N.
If you actually LIKE the Public School curriculum then it is a good way to go. It's mostly computer based which I can't stand and they are also very hands-on with the parent, which I can't stand. BUT for you, if you like that, it may be good.
If you are kept from private curriculae designed for homeschoolers, I'd be happy to point you to any number of inexpensive HSing choices or academies that offer payment plans and that are very affordable.
OR you can do what we do, and simply design your own curriculum, without paying anyone a dime. :)
