I just started my pn program and we were told we'll have to take the hesi all three terms; one the first term, two the second, and three the third. (at least I'm pretty sure that's what the teacher said) How exactly do these work? And what would be a good study guide/book to use? I see books for entrance & exit hesi exams, but what should i go for when i have one every few months? This just seemed confusing to me..any further explanation or advice would be greatly appreciated Thanks in advance.
