There's no seen fieldwork in this exam. There's unseen fieldwork and the pre-release. Make sure you know about the pre-release and the general idea of it, as you'll be asked questions on it. You'll need to use your knowledge from across the course, esepcially with your 6 and 9 markers.
There will be some maths (nothing more challenging than foundation though), so make sure that you know your range, median, mode etc.
For unseen fieldwork, it would be best to revise the key terms and know the different types graphs used to represent data.
