Offers nothing
I assumed that given the close relationship that the economist has with the mba scene, that this would be a useful prep app for gmat. I assumed wrongly. I think I may have found 1 question in the hour or so that I've been playing around in it. It's predominantly a filler app to tell you about what the gmat is - ie all the things you can find out when you Google "what is the gmat". Pretty disappointed from the Economist, but it's free so I guess I'm not crying any tears. *delete and start again*
