Picture them in their underwear!!
Just kidding. That one never worked for me. Eye contact is good! Also, if you are going to use visual aides, you could make some copies so they can keep as notes to remember you by.
You have some great suggestions going on !!! I like all of them. Right now, the one about studying skills seems the best, because t hat is something I don't have and didn't get out of high school
Best of luck w/ your interview !!
