Another tip that my teacher gave us was that if a question in section A asks you to examine the effects (or something along those lines) a could way to tackle it is to group them into environmental, social, economic. Equally if a questions is about influences on something i.e. location of industry or the like you can group them into political, economic, physical. She has told us that by actively stating it even if it seems obvious can put you into the higher mark bands.
The other big tip for section A we were given is use as much terminology as possible i.e. if somewhere is able to sustain a larger population than before say that its carrying capacity has increased rather than "more people can live there".
Like someone else said also try to consider sustainability and even if everything points to it being unsustainable maybe point out that like Boserup hypothesised technology may be able to improve the level of sustainability.
