You should concentrate on your education - especially your degree and masters. You could go into a little more depth describing modules that are relevant to your application. Also mention any part-time work, voluntary work, or one off events/expeditions/field trips/research you have taken part in. And don't forget to mention hobbies and interests. You may not have a lot of work experience but I bet you have a lot of other things to write about - just don't forget to keep it to one or two sides of an A4 sheet :0) Charlie.x
