We ordered the textbook after starting the course because my son found it helpful to have the lessons to refer back to. I was hoping to separate the lessons from the practice sets, but they are continuous. I still really appreciate being able to mark the pages he was referring back to frequently.
We really appreciate having this textbook available. It helps my child stay offline as much as possible and reduces screentime, which is especially helpful for reducing the visual strain headaches my child gets. Thank you for providing this resource!
