If there is a study group, join it. YouTube is an excellent, underrated resource-- along with iTunes U. Maybe hearing or seeing the subject matter in a different format, from an outside source, will be beneficial. I'm not a math wiz-- and most of it goes in one ear, jumbles around for a while in the cerebral cortex to form just the *right* amount of migraine symptoms to make me want to off myself, and them flies out the other ear. However, watching the same stuff I'm learning in class on Khan Academy makes it palatable and I *get* it. Get the "For Dummies" on your iPad or Kindle
instantly and use those as well. They help. Trust me. In PN school I used the anatomy and physiology coloring books to learn. People laughed at me, but that was an A course in both sections for me, whereas others failed out. Do what works for you. My "do-or-die" subject was urinary in med-surg. I don't know if it was me, or the professor, but that was my 75 almost the whole course. The final was my saving grace. Scored in the high 90's and ended with an 84 overall. You can and will do this. Don't give up!
