Failed a&p twice...

Honestly, failing A&P twice is extremely detrimental to your chances of being a candidate for a nursing program. Since it is a key class and plays a huge role in all the classes you will take in the nursing program, if you have been unsuccessful in passing the class twice, it might be time for you to reconsider. I'm not trying to be mean or anything, but that is how most schools will view your application. I would ask some of the nursing programs that you are applying to if they would accept your A&P credit if you passed the 3rd time, but I know a lot of programs would not.

As for being successful in A&P, I watched videos on YouTube. Khan Academy was extremely helpful and simplified a lot of the bodily processes.

I honestly cannot answer your first two questions. At my college, we are only allowed to repeat a pre req twice, but other colleges may differ. See if you can find one that will allow you to retake the course a third time.

As far as studying goes: I went to class every single time. I did not miss even one lecture. I took handwritten notes...for some reason I retain the information better when I hand write things instead of typing them out the first time. Then either a few hours later that night or early the next day, I type out my notes while the lecture is still fresh in my mind. I typed them onto a website called "Evernote," and the notes synced with my phone (which was wonderful, because as long as I had my phone, I had my notes with me everywhere I went). I also made online flash cards on quizlet, which also synced to my phone; I would try to make the questions harder than my teacher's tests were so that I knew the information backwards and forwards. This was time consuming, but I knew the information so well and got an A on every test.

I have a friend who struggles with testing anxiety. I do not struggle with it myself, but I really do feel for you. She's so smart, but tests are a nightmare for her. Good luck to you.
