The detailed syllabus along with the 2007 past paper and mark scheme can all be found here and it is really useful to have a complete copy of the syllabus so that you can ensure that you are revise what the examiners will test you on.
It may sound silly but watch these videos on how to maximise your efficiency in revision, it will help you gain that A grade that you want at IGCSE so that you can go on to study IB Geography with no worries!
These are my personal favourite ways to revise, you may think differently but it never hurts to try out different ways to revise as it really does help. Also try going round to a friends house to revise, yes chat and eat chocolate but also use the time effectively and you will be able to double your revision effort, two brains are ffectively better than one sometimes.
