There are more dates than just September here:http://www.kingedwardthesixth.org/2016_brochure_20150424104102.pdf
BV - July 2nd - a Thursday late afternoon/ early evening
Camp hill boys - is only sept after the exam to be fair.
KEA - Saturday 27th of June 9-12.
To be honest open evenings were really crowded (we've visited camp hill girls and five ways in the past) and it is very hard for your child to get a sense of the school among thousands of people. When small fry was offered her place at camp hill they did offer a visit during the school day with a range of dates. It was a small group - maybe twenty kids with one or both parents and incredibly reassuring to have a calm, ordinary school day playing out around us. Teachers seemed friendly - maybe because they new she was coming - much more pleasant atmosphere to see the school frankly. Helped settle small fry about going there.
