Microbiology Blues

Well here I sit nearing the end of my 4th quarter of an 8 quarter RN program...almost halfway done.
I have done okay so far A's and B's..and the program is considered accelerated because they combine pre-reqs in with the core nursing classes...and then I started my Micro II class...my micro 1 class did nothing to prepare me for the micro II class. The class is taught at a medtech level and I and my fellow students just feel lost. I am actually failing the class and do not have the option of dropping and retaking it. The school allows for me to fail and go on with my class into the next quarter as micro II is not a pre-req for my remaining classes but I need it to graduate and the school seems hesitant to give me a straight answer on "when" i could retake the class if I do fail. All they say is if I withdraw from the class I will be withdrawn from the RN program (I actually think there is a $ issue...school is for private for profit).
I'll be honest I was doing well, learning a lot, practicing my critical thinking everyday even when not in class, and boom...my first major stumble, and gang, its got me shook.
I am now the last "male" in my class since losing the other two along the way and as silly as it sounds I almost feel a certain obligation to stay with my class at all cost to represent men in nursing. The class in general see's me more of a mascot I think since losing our other two men.
Oh well just wanted to drop my rant somewhere it would be understood. Whats really bad is my wife is a microbiologist...one of those kind that can look at almost any slide or plate and identify the organism instantly, and she is just flabbergasted..and I think abit disgusted, that I can't comprehend the material. AND before you ask, no having a microbiologist in family does not help as much as you may think....Stephen Hawking explaining string theory to me wont make me understand quantum physics any better then her talking waaay over my head on microbiology.
"whew...someone get me a beer..and I dont even drink"
wish me luck
