it may be an idea to post the SOW that you might like to include so that we can see if we have anything that you can use!
Personally I'd have thought that having as wide a range of schemes as possible would be the ideal. If there are 2, 3 or more covering one particular unit from the QCA scheme that would allow people to see how other people are working and make use of a wide range of ideas from other schools.
In terms of the QCA schemes the areas that haven't been covered in as much depth as I would like are those listed at the foot of this posting - some of them sit in the ptional study units, others are areas that haven't been prioritised in my older schemes of work or in the submitted schemes. (Also, in one lesson a week I simply don't have the time to cover all of the study units that I'd want to in as much depth as possible).
