I'm screwed

Tomorrow is my first exam in Biology. 45 Multiple choice, 15 true or false. That's it. Only one problem with that: I do better on essay tests. Word association is not at all hard, but that is where I seem to always give a couple wrong answers. You know....a simple twist in the wording and that's all it takes.
On the other hand my essay exams are always spot on. I am the one defining the question. I am the one wording my question. Even if I'm not sure of the question, I write enough bullshit so that somewhere in there I am at least touching on the subject enough to make the grade.
I have been out of high school long enough to have forgotten those ancient subjects of sciences, maths, languages, etc., and had educated myself with what I've seen, heard and tasted of the world at large. Thus going back to school after 30 plus years was a tough transition.
After years of thinking that life can't be enjoyed without the use of booze and dope, I cleaned my act up and have been free of both for over 5 years now (cigarettes as well). I decided to go to college to see if I had enough brain cells left to at least get an Associates Degree in Social Work. I wanted to get in to the drug and alcohol field in some lower position and work my way through. I want to give back to the community that is plagued with the abuse of both.
During the course of my 3rd semester I realized that I could make the grades and have now decided to go on and work towards a Bachelors Degree. Anyway, I was between my 3rd and 4th semester when my wife had her stroke, so at the start of the 4th, I had to drop two electives to free up time so as to spend more time with my wife at the hospital. So instead of graduating this past May, I am currently in a 5th semester of which those electives are being finished up. I am attending a Community College with plans to transfer to Carlow University in the Oakland area of Pittsburgh.
Getting back to the original point of this story, I will not start to sweat this exam until the instructor tells us to put all our belongs under the desks.
Maybe I should start studying...
