An invaluable resource

Over the last few months my son has been using the resources on your site in preparation for an 11+ exam. We both find the site, practice papers etc. to be an invaluable resource. The Chuckra material is excellent. I totally support and agree with your view that the current exam is not a fair test. Whatever the result of the exam I know that my sons confidence has grown immensely using the Chukra material. Could you please confirm an address that I may post a small donation to.
