Hello,
Before doing the test, you should ensure you are familiar with the server Rules, you can find them there :
For the scenarios, you should think on how they would happen in real life, follow the rules and always ask yourself if this would be realistic before posting your answer.
I don't think we can be more specific with the scenarios to help you because it would be cheating.
When your application is denied, you usually have a reason for each of the questions, so make sure to takes them into account.
