Over on JF someone posted about the ability to accomplish the test via the iPad.

Haven't done the test, but did get to the learning center on my iPad during a layover.
As the Kasa de Kronan comes closer to being empty nesters and free to travel whenever, it's something I intend to do in the future.

For right now, prefer to travel with Award tickets or simply pay the $$ to avoid the stress. Might change the mind if the kidlet's HS goes to full online again.
