We used Rod and Staff curricula up to 8th grade then switched to Abeka. The problem with Abeka is the math. It spends way too much time with the wrong kinds of things for kids to get proper exposure to math. I got through a year and a half of college calculus in pursuit of a Math major and didn't do half as much algebra as the Abeka book had. The Geometry book is even worse.
Abeka is wonderful on History and social studies and science because it is such a strong Christian perspective. My 18 year old has 10 times more knowledge of history than I do at this point after going through that book.
We learned that it is very literally easier to teach your child to read than to teach him/her to do the dishes.
We use Abeka and Saxon Math atm. I find them to be quite good and my son likes them. He finds it a little difficult because teachers have been giving questions to the tests beforehand. He’s actually having to learn HOW to study.
