Economics A Level - what do I do?

I have been getting Ds in economics and we are now only a few weeks away from exams and I'm panicking, because I think best case I'm going to get a C - (Both my teachers aren't economics specialists and have both never taught it - so its been quite hard but I cant fully blame them as I didn't put any effort in year 12)

I'm not sure if you already watch him, but, EconplusDal really helps me understand some of the tricky concepts or even definitions in econ. I'm not sure what type of learner you are but I find videos really useful so there are loads of ones on his channel or tutor2u uploads some helpful ones too.
For topics you find really tricky, UpLearn is also good at explaining and giving questions. They have a free 3-day trial option so you can skim over topics (my friend uses random emails to extend their trial - not sure if this will work, but it might be worth a try?) It's probably not the best idea to buy a subscription now because it's expensive, and unless you were using it 20 hours a day, most of it would go to waste hahaha but yeah the trials are deffo worth it cause they're free.
If it's exam technique you're struggling with, I think familiarising yourself with the structure of the mark scheme is helpful. For extended answer questions, they all follow similar, if not the same, patterns. For my exam board, it's define the key terms mentioned in the question, make points relating to the command word (discuss, evaluate, to what extent, etc), give an example/application, analyse and evaluate (limitations, it depends upon, long term effects).
Hope this helps! )
