I HOMESCHOOL my son

What to know where I can get more work books tesxt book at

I may not know the answer fully, but I want to make sure of one thing. I was a homeschooled child and then my mother moved and I began going to a public school. I had to be brought one year behind because the books my mother used weren't accredited. so when you get those books ask to make sure they are accredited especially if and when he is in high school level. PLEASE. it's so important.
