Did you get a chance to watch the info session? They haven't posted the slides yet from the 9/22 info session, but they said they would post them soon.
They said that the proctored essay has 3 scenarios to choose from. They want to know if you can write/think critically, are you thoughtful, and did you actually answer the prompt. A tip they had was to "take risks" and to "treat the whole person".
There will also be 3 math problems, drug calculations or conversion type problems. They said it was basic algebra type problems, and you could find some practice problems online. However, they kept saying that it wasn't supposed to be too deep or too complicated, and that anyone in their office (admissions peeps, not nurses) could do them.
I haven't listened to the things here but there are some topics with audio associated with them on this page:
