ColCHS do not have open days as such. What they do have are open mornings where you are shown round by the year 8's. You can't just turn up though and have to make an appointment. I guess this is to ensure they are not swamped. The dates for this year can be found here:http://www.colchestergirls.essex.sch.uk/?_id=727
There is no NVR paper in Essex. VR is all multiple choice but the Maths and English are not. However, other contributors to this forum will be better placed to answer.
Thanks, I was sure I'd seen some dates for open mornings, but when I tried to find it for a 2nd time it completely eluded me!
