Sorry if I've misunderstood you, but is it not the case that Latymer will not be doing VR this year?
You are entirely correct, NLM. From the Latymer website:
Parents of those children going on to do the Literacy and Maths Tests will be advised of the test time and further details. Parents of children whose scores fall below the required level on the NVR Test will be informed that their application is unsuccessful and of their right to appeal.
There is no VR test for Latymer this year, so you should not be preparing your DD for VR, 2Girlsmum.
