If your paramedic program is like most paramedic programs, you will pretty much neglect the basic sciences and get a crash course in anatomy+physiology that you won't have the foundation to really understand. You're going to spend the next 12-24 months learning about very specific things in a narrow slice of medicine/science. IMO, the best way to set yourself up for success is to learn as much as you can about general chemistry and biology so that you have something to build on top of. https://www.khanacademy.org/science/chemistry https://www.khanacademy.org/science/biology
