Maths Scholarship Test (King Henry 8th)

[no_ball]

DS has been invited back next week for Maths Scholarship exam, lasts 45mins. Does anyone know of appropriate practice paper or suchlike or is it down to natural ability now. His last exam was next Tuesday; not now with this letter out of the Blue!
Do Solihull or KES also call back children for exam/tests or just interview if they are bright enough to do well at the first stage?
