BBC site is well known and well used and is recommended. Good interactives, you are able to revise and test. Remember to record the TV programmes that accompany it. Dates and times of geography programmes will be posted later.
S-cool is a nice, clean unfussy site which I like. It offers a simple breakdown of key ideas, has an excellent Quick Learn section with graphics and test questions.
The Geobytes site offers much useful guidance and provides regular updates on geography on the news. Well worth a browse.
The Avery Hill site covers your geography syllabus and offers exam revision guidance and examples of past papers. Recommended regarding specific revision advice and hints and tips about answering exam questions.Also includes definitions of command words.
Watch this site for further updates and guidance.
