I'm a current student at Marian in the ABSN program, I'll be graduating in December. Regarding the experience, I think its better than it used to be but I think to some extent all nursing programs
are sometimes disorganized. I recently spoke with someone who graduated from IUPUI's and she said theirs was super disorganized too.
As far as classes go, some instructors are wonderful, some are not great. They are all online classes so you have to put in the work if you want to see results. I would recommend getting a study group together if you learn well that way, asking for help when you need it and reaching out to the Prof. The main disorganization I see is with our clinical groups, they often change at least once. Yes its annoying, but I've heard that it happens at other schools
too. As far as clinicals all of the clincial instructors I've interacted with are wonderful! They are nurses with lots of experience who really know their stuff.
As far as NCLEX pass rates, I've heard its high (like over 90%) but I'm not sure the exact number. Also the accelerated program has a super high rate of students who get hired directly on at St. V, so the job security is pretty nice.
PM me if you have other specific questions!
