Yes, the key to doing well in business is memorising the syllabus word for word.
But I'd have to disagree with you a bit there, business is one of the most simple subjects to cram because its so straightforward
I recommend keeping up to date with business news, and find companies to use as case studies that you're genuinely interested in, because you'll find it much easier to recall and use them as examples in the extended response.
Don't go overboard with notemaking, make them at the end of each topic you do and keep them brief and concise.
And make sure you can write good business reports. Practice and hand them in until you're confident using headings, incorporating case studies etc.
