We used this program with my fifth grader and spread it out over a year and a half. The last few chapters are more advanced grammar concepts so we put those aside for later. If I had to do over, I would actually begin this program at 7th grade and continue on with it through 8th. It fits very nicely with the Charlotte Mason concept in that the lessons can be broken down into smaller portions. And I agree with the others in that this program is rich in English language history, so you get more than just grammar.
