Your Notes
Good revision is not just learning the geography but also learning how you use it to pass your exams.
Revision begins as soon as you start your course. You can prepare by:
Finding out what you need to know.
Organizing your notes - make a list of the topics and case studies.
Knowing how your GCSE papers are structured and practising past questions.
Make sure you have a copy of the syllabus, be really clear what topics you need to know then check that your notes are complete and make sense.
Most exams have compulsory questions so you can't afford to have gaps in your notes just in case those topics come up.
Write clear and complete notes when you do the work in the first place.
If you need to improve your notes you could ...
Ask someone if you can copy up any work that you have missed - but make sure you understand it.
Find extra information on topics using textbooks, the library or the Internet. There are many sources of information but for it to be useful make sure that you fully understand it - if not ask your teacher.
Get a good revision guide. There are lots available in the bookshops and there may be one specially designed for your syllabus.
