i dunno if it's different when getting your bachelor's degree, but i think nearly all of our students have completed a&p I and II and micro. and such before starting the program. then again, our program is super limited (waiting list, etc.) and so the more classes you have done when you apply, the more likely you are to get in.
Do you mean that you have to complete all those requirements (A&P, Micro, nursing classes like nutrition/pathophysiology/etc), and then apply to the final two year part of the program? At my school, all of those general requirements are done in the first two years (ideally), called 'lower division', then if you progress, you can apply to 'upper-division', which is the final two years. Upper division is pretty competitive, but you onle need to maintain a 2.7 to progress through lower division.
Advisors at my school's nursing college suck, because they make you take all of the hard classes the year before applying to upper division. They should split them up, so that you take A&P I your first semester of freshman year, then A&P II your second semester, etc. I know we make our own schedules, but some kids really trust advisors. Why give some of them false hope all throughout freshman year, and then give them the tough classes when they might feel they are in too deep?
Most of my teachers use 100-90 A, 89-80 B, 79-70 C, and I forget what the minumum for a D is. B+, C+, and D+ are also possible for the extra .5 (a B+ is 3.5 towards your GPA). Some teachers followed the scale actually reccomended by the College of Nursing and used 100-93 is an A, then I forget after that. One of my teachers used that scale, and even though I got a 91, I received a B, not even a B+. I wouldn't care so much if another kid couldn't take some other teacher and get an A for a 91, in the same damn class. Inconsistencies like that piss me off but hey, what can ya do.
