hi there, i cannot offer any advice i am afraid, but, it is nice to find someone else who is working towards Kendrick, my DD to is studying towards the entrance exam this year.
we are using the NFER recommended papers and also some Athey educational ones, which were very similar. as well as some online NVR tests which are more like games, to try to make it a bit more "fun"!
my DD does very well with VR ( usually 97%) but,not so well the NVR so, we are still working on those!
I have struggled with wanting her to be as prepared as possible, but without pushing her to much, it is difficult to know sometimes how much preperation work to do, i find.
Haven't tried the Susan Daughtrey books although have heard they are very good.
good luck to your DD
