How many pupil in one class in adult nursing usually?
Adult nursing classes can be anything upto 50 - 80 people per class cohort depending on how many successful students were offered places for each year as the university will divide the total amount of people into equal amount of classes/ cohort.
With midwife students there's only a limited numbers of students each year taken in which can be for example 40 students and maybe divided into two groups/ classes so that one class will be on placement while the offer is at university studying weeks.
How many pupil in one class in adult nursing usually?
As many as the university can fit into a classroom. The university local to me has cohorts of student nurses of 100-150 - sometimes they're all in a lecture together, sometimes split into smaller groups. (I only know this because students regularly tell me while on placement)
