Maybe it's an indicator we have it about right when I'm told to make the language stricter and less strict.
First of all if you fail the test, you can have a second chance. If you fail it again, you can get a meeting with the citizenship judge. But one thing in your question with which I agree is that the language in the book is somewhat more complex than it need be. One of the things we want to do is to make the language in the book more comprehensible to more people than it currently is, and I think that would also impact the tests. If we can make the language simpler and more direct and easy to understand, I think that would be an improvement.
