Hi I study english lit and lang too, as well as geography. For section B, question 7 is usually linked to hazards, either hydrometerolical such as the distribution of typhoons or linked to El Nino and La Nina, or geophysical and linked to tectonic activity. Question 8 is usually linked with global warming and sustainability which is where the Africa and Arctic case studies are brought in. Question 9 is linked to globalisation, global development and is where TNCs and trade blocs and global groupings come up. Question 10 is linked with ideas about population and changes to population, migration (you could bring in Poland/UK) and ageing population. If I were you i'd pick one of the units you're the best at and really revise it, see which case studies you could try and bring in.
