Probably a good call to refer to local businesses if thats your choice! It's a pretty popular CBA 2 topic from what ive gathered, so it may be a good idea to see if you can directly interview/discuss with anyone who runs their own business locally to grab up some extra marks and distinquish from classmates! Refer to terminology and topics in your course as much as possible if you can, and try to relate it to things you've done in class (If you've done budgets, for example, you can maybe include something about how a smaller business could manage their budget, and the kind of things they would need to have in their budgets that large corporate businesses wouldnt, or the other way around!). Good luck with the CBA!
