This curriculum is well worth the money. I was quite hesitant to purchase, but I and my son are so happy to have done so. To say it's well put together would be a vast understatement. He finds it super challenging in a very good way. The bite sized daily lessons that we have broken it down to are perfect for us. We did find that trying to stick with the breakdown of what should be done weekly was a bit too much for us. We tend to school all year long, so taking it down a notch was no big deal. I also love that he can work almost independently. Besides helping with answering some questions regarding new concepts the only thing I assist him with is the Literature. It could be done alone, but it is set up for a teacher to help. We have found that way to be best for understanding and also because we find it quite enjoyable to do together. Overall, we couldn't be happier with this program.
