I like this guide and I am using the ideas from it.
I must admit that when I first got it, I was a little disappointed. I think perhaps I was expecting something different. I read through it, and I set it aside for awhile.
Then awhile later, I began thinking of index cards again, as they are so compact and I felt I needed them to help organize our schooling. However, I felt a little at a loss as to where to store them. So I emailed the author. She emailed me back very quickly with helpful suggestions that got me thinking.
So now, I have made up cards for each of my 4 kids, and am using several of the ideas she has. Also, this guide includes the many specific items that you might want to include, such as definitions of math and English terms. This has made it easier for me to use for that purpose.
I found this was a purchase I am happy with.
