I would not bother with skills at this point, too late unless you have a firm grasp of the concepts - maybe watch a video on synoptic charts or something.i still haven’t started, i managed to pull out some motivation to study for my other exams but i am 100% over this now
As above, move through the past papers but most importantly know your case studies. If you can't bother with statistics, fine, you can make them up if your school does some obscure enterprise/ecosystem like mine does. But be able to give a detailed statement on the nature of each of your case studies - for ecosystems at risk especially, you really really really need to know how a couple of organisms interact with their environment and each other. Adaptations, that sort of thing.
Something as basic as how coral polyps and zooxanthellae have symbiosis, how mangroves have special snorkel roots to deal with waterlogged soils, it's not very hard.
I just do Sydney as my large city in the developed world for urban dynamics, just do whatever your local town/city is if you are truly fucked when it comes to that module
