Sorry for the late response; didn't see it until now! I would say that the Pre-Health program isn't that hard but is a lot of work. Of course, this is coming from someone who is strong in the maths/sciences so I realize it might not be this way for everyone. If I had to rate the math I'd give it a 3, and the chemistry I'd give a 5. It also depends on what courses you've taken in the past; I took math and chemistry at the U level in grade 12, so I'd already covered most of the material previously (albeit years ago!) I never took a straight biology class before Pre-Health, but I took anatomy and physiology when I studied animal care a few years back so there was some overlap. How difficult you'll find these classes all depends on whether or not you've studied similar material before. Some people didn't have much of a background in math/chemistry, and it was really challenging for them. My advice would be to hang around class slightly before and after class and ask the teachers questions; show that you want to make the most out of your time there. A digital recorder really isn't necessary as most teachers post their powerpoints on Blackboard. However, still develop your note taking skills as teachers won't do this once you enter your nursing program! Good luck!
