Useless with only set of questions
Great idea, but with only one set of questions you cant retake the test.
Should be free. 80% off or not. More questions, enough for 10-12 tests maybe. And while accuracy might matter, a 40 minute mandate makes it somewhat innapropriate for the iPhone platforms general usage. (thats a generalization obviously, but 40 minutes, uninterupted... come on)
