I wasn't thinking about second guessing questions, it was more to encourage "active" reading eg to underline key words, dates, character names etc. I understand your point though.
Did you order last years test? It would be good to have your child sit the test as a mock and see what needs to be improved.
I had my DD sit some mocks with a tutoring company that was specific to the CSSE test and found that where my DD needed to highlight text was the actual questions, for example "choose two
answers that mean the same as enchanted" My DD would only tick one answer instead of two because she rushed the reading of the question.
It was the silly errors we had to worry about, plus the fact that she is always away with the fairies! Didn't help that she was only 10 years 2 months old when she took the test
My DD loves reading so I always sold the reading part as the best part of the test because she gets to read something interesting and go into her own little book world
