Hi dereksurfs, RootAnn, and fastforward,
For what it is worth DS is a slow-and-steady-perfectionist kind of guy, so I can easily imagine that others could complete the work in less time, but just how much less is a good question!
You will recall from my first post we are from Australia. The school years in my state are from K-12, with high school encompassing 7-12. We do not use a 4 year high school transcript for university entrance, rather the students within the school system complete a Higher School Certificate (HSC) in 11-12 to obtain an Australian Tertiary Admission Rank (ATAR) which determines their eligibility for university places. Homeschool students often return to the school system for 11-12 or pursue other pathways to enter university.
Therefore, I don't really feel comfortable commenting on how the course fits into US high school and middle school expectations. DS 15 was in AU Year 9 in 2014 (moving AU Year 10 in 2015) and the level of work (according to the description "designed for 9-11") seemed like it would fit. And fortunately for us so far it has. The syllabus along with the TOC for each level of WWS gives a pretty clear idea of the workload required. If I had to hazard a guess, I think I would agree with Derek when he says "...this is not a light class. Rather it's a serious, college prep, high school writing course."
I also happen to agree that "writing for 2+ hours per day in this class" and then "having to write some more for other subjects... all in a days work" may have proven a bit much and have adjusted my output expectations for other subjects accordingly. And for me that is a perfect demonstration of the beauty of homeschooling.
