Don't get so hung up on the numbers, as long as you pass. I didn't do that well academically...in fact, a lot of subjects were tough to pull off as a good C which was standardized for nursing students to stay in the program, period.
I had to have tutors for pharacological nursing calculations and formulas, and in the cardiac portion of the anatomy and physiology.
So....didn't end up scoring too high on the nursing boards, either. I take tests poorly. But can and do remember the important stuff and apply it aptly to life's situations.
I'm a darned fine nurse and grades no not really matter at all when it comes to true and heart felt nursing.
Skills, integrity, empathy...these are the heartstrings and soul of nurses.
