claig,
Chuckle, but quite. If the exam is a test of historical skill, it isn't a test of translation.
The point of an exam has to be to test the syllabus. What I think you are arguing for is a more demanding syllabus which puts more emphasis on use, application and understanding in maths. You are at odds with Gove there, at least as far as primary is concerned.
Obviously, people always go further than the syllabus. Equally, they fall off the other end to varying degrees. And a C is not the same as another C, it's a grade band. That is why teaching and learning in schools is not the same as teaching to a test, and can move beyond the syllabus when required.
But if the syllabus is not deep or broad enough you change that, you don't just set an exam which bears little relation to it just to make it hard.
