Trinity Croydon, 10+

[BeCyanPeer]

Hi all,
My DS failed the 10+ for trinity.
He currently attends a local prep school in bromley and out of 6 boys who sat, 2 got in.
I will begin now to prepare him for the 11+ but I just wondered if anyone else had been in the same situation and had any advise?
TIA

I have a friend who's son failed 10+ but passed 11+ for Trinity and was offered an academic scholarship.

What prep, if any, did your son do?
