Well I was confidently leaving it all to do in the summer holidays as for the two older siblings. I knew they had thrown in a couple of extra spatial reasoning questions int he last few years, but didn't realise that the name of the paper has actually changed to Non Verbal and Spatial Reasoning. This makes me wonder what else I have missed. I had him read the GL 'Explained' books before the mock tests, but now I need to research and find out what else we need to do. The practice papers that QEHS Gainsborough suggested similarly do not contain the Spatial Reasoning questions, so I am on a hunt for resources!
I'm not panicked - yet!! But any tips well received

You’ll be fine. We didn’t realise about the paper being Non Verbal and Spatial Reasoning until my daughter came out of the test, as we’d just done the preparation recommended by the school (which didn’t mention SR, and the practice tests they suggested we buy didn’t cover it.).
That was still enough to get my daughter in from out of county - at the end of the day, these tests are intended to assess children’s natural abilities, so familiarisation with the test style and structure is sufficient; no need for specific training. My daughter really liked the Spatial Reasoning section because it was something a bit new and different for her, and she said it was all very straightforward and easy to understand anyway.
Maybe just look for any Spatial Reasoning practice test, and let your child have a go at them to familiarise themselves with the question types, but I don’t think it’s anything they need to have much (if any) practice with.
