Having time to complete it.....are you referring to all 8 levels of CGE? DS is in 3rd grade and we are on book 3. However, do to unexpected circumstances this year, we weren't able to start when I wanted and it has been slow going. We will be continuing with book 3 into 4th grade. He is, for the most part, on the same level with reading and grammar, but a bit behind in writing. I figured we would have to slow the writing sections down and possibly add to them. I was under the impression that if it took us longer to complete all 8 books (say not done with the entire series until 9th or 10th) that we would still be at a good place. Do you believe this to be the case?
