Higher Modern Studies - Inequalities Help??

Hello,
I am sitting the new CFE Higher Modern Studies and have no qualms about what I need to study for the Democracy unit or the World Powers one. However, for the Health and Wealth Inequalities in the UK topic I am struggling with what to revise and what sort of questions possibly could come up? In class we have covered gender inequality and social class stuff - but I am not sure about what I need to cover and desperately need some help. If anyone has any tips or has revised for this topic, please can you share what you are doing? Many thanks.
