Current edition being used now. My son just used this last year. (I had two student work books and test booklets so my daughter could do a few pages as well) -Teacher key has no writing excellent condition Student Work-Text has about 14 pages written in out of about 375ish. This one was my daughters and she barely used it because she was using another curriculum at that point. A few of the pages in the mid book are torn but not used and I just clipped them together. I also have a Quizzes, Tests and Speed drills booklet I’ll throw in for free. I have another student workbook available too, but it’s the one my son used and he stopped at lesson 79. Ask about it if you need another one.
