Thanks everyone for the replies, especially Fretwanger.
I have one small question regarding the format of the cube tests.
Does each indivdual question show "one cube" and then 4 exploded choices which can be "folded" into the cube.
Or
Is it the other way round with "one unfolded" example and 4 cubes, (shown at different angles) to choose from?
Would be great if someone could remember as I'm about to make a cube, a few dummy test papers and bug the family a hell of a lot......
