it was alright

you might want to add a righclick disabler function so people couldnt cheat

Uhhh.... what?

Not sure if it's intentional, but "Missisippi" has 4 S's, not 3. Also, a persons opinion should not be used in a quiz (i.e Black Ops being better than Modern Warfare 2).

But Portal music, so.... 5.

Not really fun or interesting.

Your first problem is that you don't know how to spell Mississippi. 4 S's.
Also, 9x2-13 = 5.
Plus you should really give some thought as to why anybody would want to take your quiz. You have to design something that people actually want to use.
