Need Advice Failed a Course

A am a Nursing student who just failed a course by .74. My instructor is sticking to "her system" that she has used for years. This is my second degree and I worked very hard to get to where I am. I worked many years full time taking prerequisites and now I am set back a year because of .74. My instructor knows that this will set me back a year and cause financial hardship. Some of the questions I missed I found in the book, but she is determined to dispute the book. I am going to take this further after Christmas. I am afraid to say too much in case my instructor reads this. Any advice?
