My dd said the last two questions were easy, but the second to last page had a tricky one, with no numbers. She managed to figure it out in the end. The last two she said were easier ones like they put at the beginning of the test and I remember the Emanuel mocks the last two were simple fractions, but before that was a tricky question (both mocks were like that) so I remember telling my dd if she gets stuck on a tricky one towards the end, move on and answer the last two, which might be easier and according to my dd it was like that. Do you think your ds is referring to the one with no numbers? If he was not able to do it, I am sure it is fine if he accurately answered the other ones. My worry w dd is she gets over confident and then might make silly mistakes on the easier questions.....she has done that in mocks. I keep reminding her that she must slow down and do all the work, not take short cuts and make silly mistakes....focus.
