Recommendation for Sutton and Kent mock test providers please

[starrystarrynights]

I've had a look on line and a number of providers undetake mock tests for the various local grammars.

Are these tests all very similar or is there a provider than someone has used that you coudl recommend?

We used the mock tests done by the PTA at Sutton Grammar School. DS1 did both of their tests and it gave him practice at going into a big hall to do an exam and it gave us an idea of his position among the children trying for grammar/private places.
