My two oldest sons were in a Christian school that uses that curriculum. My only problem with it is that they were sooo easy. Both boys came out with high grades, but little knowledge retention for the following school year. They are all workbooks, which can be okay, but it was entirely self directed in this school, as it is in many. Without a lot of teacher input, it teaches independence, but also can be detrimental to the student with any learning needs that are unaddressed. If your student is capable of mostly unaided learning and is very bright perhaps it would be a good fit. My two boys both had wonderful grades , but did poorly when I began homeschooling and really checking their knowledge. Just some thoughts, I hope that it helps you.
