It really isn't that hard for a course. I understand that scopes of practice vary among states/provinces, so your class may have a bit more info than mine (we don't do IVs, for example), but really, don't stress. We had 17 people in my class and only 4 of them were unable to pass the final on the 2nd try - our school allows 3 times, I don't know how they all did on their last attempt. For a class that doesn't require any prior education beyond high school, I think a 75%+ pass rate is pretty good. Just don't overinterpret the questions on the written exams and stay cool during the practicals, and you'll ace it. I would say only 1 of the 4 people who had trouble passing was what I'd define as, um, of inferior intelligence, for everyone else it was just a matter of nerves.
