I'm still confused as to what this app does. Does it provide questions and answers from the books shown or is it just a timer?
It is a grader/
error log and a timer. It also has flashcards (idioms) and math notes.
It is worth the investment due to the time is saves you from having to grade your
OG 11 or 12 mpc's. If you're studying for the GMAT and have an iPhone, then it is a great app to keep track of your
OG performance.
It does not contain answer explanations, it simply grades options 'A' through 'E'. If you're 1) organized, 2) able to keep track of all your answer sheets for the 1000+ questions in the
OG books, 3) don't mind searching through your papers & keeping your %-age correct stats, 4) prefer writing out all your (1000+) answers on paper & don't mind flipping to the back of the book each time you want to check your answers, then you don't need the app.
It saves you a few minutes from having to grade and keep track of your grades (a process you will do several times while studying the
OG books).
