You might also want to change the mentality you have going in. Be enthusiastic about each passage. "I ALWAYS WANTED TO LEARN ABOUT NATIVE AMERICANS WEAVING RUGS AND SHIT." I'm under the impression that the RC passages are all pretty legit and educational. View them as an opportunity to increase your knowledge about stuff you wouldn't have even bothered to think about. You'll be able to increase your arsenal of "bullshit" to spew during dinner parties: "Oh yeah, I'm totally cultured and shit. My favorite artists is that Noguchi guy."
I thought of this advice today when I was doing the RC section of my practice test, and it did seem to help.
I am sure there are other really good but not standard tips buried in assorted threads - maybe we can collect them here.
