For West Berks - I found this on the web-site:
"Notification of allocated places for the Year 7 allocation 2012
Letters are sent in the post on 01 March (2nd class) to all West Berkshire applicants. Parents are asked not to contact the admissions team by phone to ask for the result because it cannot be communicated in this way. Applicants who make an online application are able to log into their online application from 9.00am on 01 March to view the result and if they ticked the box to be notified by email, will be sent an email as well. The emails will be sent from our server first thing on the 1st, but due to the volume this can take some time."
But RGS send out their own letters (SAE 1st class), so should be tomorrow or Friday by post!
Which is around 2pm here
