Audition advice for those without inpatient experience

My school didn't give me an inpatient IM experience (insane I know, yay DO schools). I'm nervous going into 4th year about looking like an idiot for my first IM audition. Anyone who has been in the same boat have any advice for how to be prepared ahead of time?

Wondering if I should be transparent with the preceptor about not having had an inpatient experience as well.
