Hey UFballerina,
The essay questions is not designed to be difficult, its rather a means to determine how you would handle a situation. It would not be fair to others if I told you my clinical case when I was interviewed however, my suggestions I gave you last time should give plenty lead way. There are 6 professors doing the interview including a 1st year student that asks questions. This creates a lot of variety. What tree would you be? Is doing PT a right or privilege? What did you learn during your observation hours? These are some examples which in my opinion you cannot study for. Most important way to be prepared is be YOU! Best of success.
