That's almost certainly my mistake. For those two cmp tests I just 
didn't know what the answer was supposed to be, so probably picked a 
figure out of thin air based on the subsequent 2 answers.

You should manually (or by some other independent method) check what the 
correct answers are for those two cmp tests and change them to 'is' tests.

Thanks for your work on this. I'd be interested in seeing a summary of 
what you've achieved at the end. Especially if you point out areas where 
the old system was getting things wrong - people may want to recheck 
their results with the new modules.
