IF YOU'VE never heard of Miley Cyrus or — more importantly — Hannah Montana, stop reading.

But if you're one of Miley/Hannah's many, many, many fans (mostly tween girls, but also a few parents), this is the test for you. Since Philly is in the grip of Hannah Fever — she's playing a sold-out concert at the Wachovia Center tonight — what better time to test your Cy-Q?

On the Disney Channel show "Hannah Montana," Cyrus plays Miley Stewart, a 14-year-old high school student who leads a secret life as a pop music star named Hannah Montana. Stewart tries to balance her time as a "normal" teen with the challenges of being a celebrity with the help of her dad (played by Miley's real-life father, Billy Ray Cyrus), her brother and her friends.
