Charity School of Nursing

I have completed the 1st semester of nursing at Charity but had to take time off because of some unforseen circumstances...I'm extremely nervous about starting back in Jan. I have little confidence and feel so stressed about not passing-- so much time and money has gone in to this 2nd degree. Any current or recent grads of Charity out there with advice? 1 thing, in particular, that I'm worried about is that (I was told) during the final semester students take an exam (which I'm told is actually harder than the boards) and if you don't pass you're kicked out? Is this true?! Any advice wold be helpful.
