Watch out for links being added to the blog to guide you to useful revision sites and materials. First of all your attention is drawn to the new BBC Bitesize Message Boards for students studying for Standard Grades and Highers. As well as the games, videos and tests for the range of Bitesize subjects, you can now post queries or help others with revision online. There are also teachers on standby to offer tips and answer queries. The message boards are moderated and you have to sign in to access them but they are available for posting daily Monday to Sunday from 9am until 9pm.
