We used MFW Ancient History and Lit for high school this past year and had a positive experience. I’ve posted about MFW high school a couple of times, but can’t seem to locate the post right now. 
I originally bought the Notgrass World History set first, but upon further investigation decided to add the pieces to complete the MFW Ancient History and Lit. One of the main reasons was the complete study of the Old Testament. I’m using this with one of our adopted children who had not had an in depth study of this nature in the past. Another reason was the way the MFW lesson plans were totally laid out and written to the student. This has freed up my time to spend with our two younger children, who are beginning readers.
In addtion, I liked the writing piece that MFW incorporates along with a scoring rubric for ease of grading the writing. I tend to be very critical when grading writing, which ends up in frustration for both our daughter and I. MFW provided a 14 point check list to use when critiquing the writing. I have seen great improvemnts in her writing since the beginning of the year. We both feel good about that.
We plan to continue with MFW World History this year as it incorporates a complete study of the New Testament. And again, I like the fact that everything’s laid out for us. I’m not sure if this dd is college bound, but it’s a possibility. I want to make sure I have all the bases covered just in case and I feel MFW will do that. I also appreciate the biblically based world view the curriculum is offering. In additon, our dd has stated on several occasions that she really liked her curriculum and wants to continue with it.
One thing I will say, is upon getting the MFW World History for this year, 10th grade, I am disappointed with the history selections. It relies heavily on and Usborne and DK books. With that said, we will be supplementing with other living history books, some are Beautiful Feet recommendations. The teacher’s manual actually suggests this for stronger readers. Apparently, the reasoning behind the lighter schedule is due to the fact that the student will spend several weeks learning how to write a research paper. This dd is an avid reader and is always looking for extra books to read, so I think she’ll do fine with the supplement.
As pollysoup mentioned, we too are done by early afternoon and it allowed our dd time to volunteer in the community.
Let me know if you have more specific questions. We’ve also used the MFW kindergarten and 1st grade programs, but not ECC or any other elementary levels.
