The test uses flash. Apple does not support flash on iOS (iPhone, iPad). You'll need to find a computer that supports flash OR download an app for the device that supports flash.
Here is a workaround that I'm told works, however, I haven't tried it myself.
Photon Flash Player for iPhone & iPadIt's an iTunes app called Photon that costs $3-$10 and claims to run flash content, it's given 5 stars, and is highly regarded. I have NO idea if it works. If you try it and it works (or does not work) please let us know.
It's also ranked #1 on a few other sites.
