For instance, both Tiffin schools' NVR and VR questions are based on NFER format. Does anyone know, in the past years, whether they ever had NVR questions that were outside of the common NFER ones?
No knowledge of Tiffin but Reading seems to use an extended NFER format based on feedback from the boys which may be unreliable.
Part of our planning has been "be prepared" for the unexpected, if the question type is new and hard then "do your best" everyone will find it hard.
So we did spend a fun afternoon looking at nets of cubes, the 2D to 3D and spatial skills are useful in developing brain flexibility. Cutting out the nets and learning the rules was a diversion from dry NVR.
