In reply to:

I can't see the students at my school scoring this poorly on a history test because I consider most of them fairly intelligent (middle class suburban school district) but I'm not sure.

Sorry, this is my King Charles the First's head. Ignorance and lack of intelligence are not the same thing.

This may or may not be an apocryphal story, but apparently after a very long and complicated explanation of some knotty technical point from one of the counsel in a trial, the judge said "I'm sorry, but I'm none the wiser", to which the lawyer replied "No my Lord, but a great deal better informed."

The students at your school may be better informed than the average, but that doesn't make them any more intelligent than people who haven't had the same quality of instruction. [/rant]

P.S. Sorry if you're feeling picked on, Jazzo.
