I did that exam too....you couldn't really revise for it- if anything you couldve done a few past papers.
That exam wasn't the easiest Geography Paper 2- infact I thought it was one of the hardest considering P2 is meant to be pretty easy.
HATED THE LAST QUESTION!
Is this the problem solving paper where you have solve a given problem using your knoledge and reason it? well.. i looked into some case studies.... u cant really revise for it (not to my knoledge anyway)
