Alleyn's 6th form / 16+ - any feedback?

[Minitoots]

Are there any 6th formers at Alleyn's (or parents) who can give us a bit more of an idea about the 6th form, in particular the Art, DT, Drama and English depts...What's the 16+ entrance exam like? We recently went to an open day and it sounds as though the chances of pupils getting in from other schools are quite small as most current year 11s stay on, and the academic standard is extremely high - any comments from anyone with experience of the school would be great - just send me a PM - thanks.
