There is a lot of great, interesting content for my daughter to learn. However, there are lots of confusing mistakes in the curriculum, such as assignments in the workbook not lining up with the assigned reading, according to the lesson plan they give. And questions on the quizzes having no right answers to choose. Also questions in the workbook that have no answers in the textbook. I also chose not to do the tests as they are sold separately and I already had to buy so much (teacher's book, student text, and workbook) for this one subject. I will find different curriculum for next year.
