The workbooks seem great and have great reviews. So far you all seem to have good things to say as well. I picked DD up the 1st grade one (she is currently in 1st) because I am not sure where she is. In 2 hours she completed the first 3 subjects. I'm thinking it is too easy for her which confirms my assumption that she is beyond the 1st grade. She is enjoying it so I'm going to leave it be and let her complete the rest of the book. Maybe I'll see some strengths and weaknesses while she goes through it.
