You need to already know geometry in order to use this curriculum. We just got it for this current school year and my son and I are both frustrated. There is no instruction on how to get the correct answer.
This math is easy to follow and use, for the most part. Some of it is difficult to follow, not explained as well as it could be, but usually can figure out. Lifepac is a good homeschooling curriculumn, and yes, I would recommend it.
Initially I was excited about this product. Each book represented a "do-able" goal and I thought this would be just what we were looking for. Now that my son has really gotten into this course we are sadly disappointed. There is definitely not enough instruction in these lessons. It leaves the student with many questions and no explanations.
