I have a few hours in flight tomorrow and this seems to be as a useful use of that time ... Basically, I'm looking for something that will drill on the current question pool and that (ideally) requires *no* network connectivity while doing this. (there's usually wi-fi in flight but it's usually crappy wi-fi). Preferably something that will run on a tablet (preserving my phone battery for when I land in Chicago) ...
Thanks!
