Just that really. I thought they merged due to falling numbers, but they have since unmerged and both now have seriously impressive ISI reports:

Are they a good place to send an academically orientated but shy DD? Are numbers there healthy now, or still low? If numbers are low, I would want to avoid, rather than risk having to move pre-pre- aged DD to another school because they end up closing once the VAT gets imposed
