Say it many times, say it until it "clicks," i don't mind the repetition. It's how i work things out, too.

Also, unrelated but not, my new favorite site for chemistry homework help: http://www.sciencegeek.net/ It's for highschool kids, but the AP section is really helping me with reviewing concepts i've not studied in 20 years, so i'm not held up in my polymer chemistry class. It has some great review "quiz" type things! Thought you might dig.
