Good to see you too, Peanut! I've gone on hiatus from posting so I could focus on trying to bang out REG in roughly 6 weeks. Hopefully I'll prove successful come the 3rd.... :-/
I would say you're on the right track. The written communication part is really nothing to worry about. If you are grammatically correct and use proper structure as you showed in your example, you'll be fine. As I said (and I've heard this from a lot of other people), the key is to use "buzz words." Here's what I mean, hypothetically: if the question were to say "The CEO wants you to explain the potential positives and negatives of using job order costing," you should use those words verbatim SEVERAL times in your response. I don't know whether or not that's even a topic they would ask about because Lord knows I have repressed the memory of my horrible BEC exam experience, but I know that if I were faced with that question, the first line would be a generic "The use of job order costing can have many potential positives and negatives for our organization" and the first line of my last paragraph would probably say "I hope my explanation has been helpful in describing how the use of job order costing has potential positives and negatives." I always made sure to tack on a little note which I thought of as my "disclaimer," saying something like "I understand that this topic can be a very complex one; please contact me at your earliest convenience so that we may discuss the potential positives and negatives of job order costing in more detail."
As you can see, it's all about taking their language and making it look like you're talking about the point. You could be 200000% wrong (which I'm sure I was on at least one of my writing exercises), and the scoring system (especially if it's scored by computer) will still pat you on the back for addressing the topic and having good spelling and grammar.
