At one MMI station, I got confused about the wording of the question and realized that I read the question wrong 20s after I started to reply. I stumbled around for a bit trying to sneak extended glances at the prompt, so I could figure out what the heck was going on in the scenario! The interviewer had to ask me clarify what I meant a couple of times. By the time I figured it out, time was just about up. Hopefully the nature of MMI allows for us to sink on one or two... unless everyone superstars all of them.
It was one of my last stations, so I think I was just tired.
I am not sure if this is protected information, but what schools have acting? In my limited sample size, I didn't have to act in either.
