Hi there! I got an A in Business A-Level and I found completing lots of long answer questions is the best way to go, because these are where the majority of the marks are. I would suggest practicing lots of these. The interesting thing I found with 20 markers are that you don't actually need a lot of your own knowledge for these as only a few marks are for knowledge, so I would suggest finding a formula to use to gain as many evaluation and analysis points as you can. If need any guidance on how to structure these feel free to give me a message 🙂
