Hi HW Mum
This is a problem that may not happen. The current predicted date of Eid is 29th September, which would give 48 hours before the earliest test date.
There are also children who sit the test later because of illness.
The question of whether these children have an unfair advantage is one of the perennial debates on the Forum, and I agree with Patricia that there is none.
As Patricia says, we moderate (or should that be obliterate?
) any posts on the Forum that might divulge information that could give another child an unfair advantage.
