Oh God. I used to score these exams for Kaplan. Of course, these are not college essays, they are SAT essays, and you don't have to worry about being boring. We're not looking to be entertained, and whether or not your essay is entertaining will not affect the score (I promise).
dchow, to answer your question, yes, it is a good idea. It is a very good idea to think about potential questions and examples that you could use in SAT essays ahead of time. You only have 25 minutes to write the thing and you need an edge, and trust me, the prompts are so boring, repetitive and unimaginative that I bet a sufficiently intelligent student from CC could pick one of these at random, shoehorn it into their essay, and still get a 12 if he wrote well enough.
I am ambivalent about the SAT in general but the essay itself sucks seriously. It's formulaic and it doesn't test good writing...it actually penalizes really good writers and teaches terrible writing skills. And BandTenHut is absolutely right that you can make anything up -- your grandfather was the first astronaut on the moon, fake statistics, fake stories from your life -- and use them as examples. And a professor did an analysis of the scores and lengths of SAT essays and found that longer essays invariably got higher scores:

The CB came out with some bull explanation for this right after the news was released, but it's true.
I always tell my SAT writing students to forget everything that I taught them about SAT essay writing after they get into college.
Oh man, Younmi, how I would love to see a Kinsey example -- I do research on sexuality
