I remember seeing that - found it a bit hard to watch in places, to be honest. It was interesting to see how other families cope with 11+/entrance exam testing in various parts of the country, but I can't understand why anyone would ever volunteer to be filmed for this kind of show.
Now the programme I would really like to see again is "May Contain Nuts", a comedy drama in which a mother sits the entrance exam in her daughter's place. I was telling my DS about it on the way to his exam this morning and he found the whole idea hilarious!
As I am sure you know, that is based on a book by John O'Farrell - which is really funny too. I loved the scene where the toddlers have a race and the Mums end up kind of dragging them to the end by the scruffs of their necks so that they can get the winner's stickers. The funniest thing is that it is all so true!
Try contacting the BBC re the programme - it might be being re-shown somewhere (though probably not on Dave).
