Well he has practised Bond comprehensions , sample papers of SWOT and some Tutions for you. A lot of NFER which he is scoring high marks sometimes above 95% and sometimes close to 90%
He is appearing for this November. He has done several KS2 maths papers and is scoring well. But we got him to appear for Slough grammar school exams and managed to score 109. So I am getting a little worried now
Don't worry, the Reading Maths exam is closer to KS2 than elevenplus, if that makes sense.
The real "test" at Reading is three papers in one day, not knowing if it is VR or NVR, the VR paper and English are not hard but they increase the number of questions so it is a test of speed and accuracy.
I would concentrate on exam technique, fun stuff and having a positive "keep calm and carry on" attitude on the day.
Your preparation looks good
