I am!!
My main tips:
1. Make sure you relate everything you are saying to the original case study, in such if you are applying business knowledge, apply it to the business that's in the question and so on...... If you don't relate to case study you can't get very high level wise because the knowledge is not applied
2. On the advantages/disadvantages question make sure you compare what you are saying, use words like 'however' and 'on the other hand', these linking words get you higher marks
3. Silly one I know, but its easy, make sure you answer the question you get asked and make enough points to satisfy what the marks are at the side
In terms of what is going to be on the paper, its anyone's guess, although looking through past papers from previous years, paper 1 tends to be more orientated towards starting up business, types of business, finance, business plans and things like that,
Whereas Paper 3 tends to be more of the running elements of a business, marketing, recruitment and things like that.
Don't hold me to it, but it does seem to have gone that way!
