Dobie Mom , you get it from https://nanowrimo.org/nano-prep-101

If you are 17 and under, you can even get a workbook centered on your grade here: https://ywp.nanowrimo.org/pages/writer-resources

Hope these links help. I use the workbooks along with the prep calendar here. It might seem like double or triple work but I find all three being helpful and works well together.
