Read the material, and pay attention during skills. For each module test I would take a fresh spiral notebook and write out every point on the exam review, then write until I thought each answer was covered. Sometimes one point would be several pages of writing. When I had finished a review, I would then read that over and over. All the time. I would get together with others and quiz each other mercilessly until we all felt confident that we knew the material. Basically, live and breathe the course. Make note-cards if that will help. If you have questions, then make sure and get them answered. Don't hold back - you are paying the instructors, make them earn their pay.
I am in my second semester of Paramedic school now, in a very challenging program. It only gets harder, so make sure this is really what you want to do.
When all is said and done, you need to do the work necessary to pass, whatever it takes.
Best of luck, and feel free to shoot me a message. It might help you since I am still in school also, so I feel your pain.
