I am not sure I really understand your question.
You can download the app via iTunes on your computer and then Sync with your iPod if that's what you are asking....
The app does not need Wifi after you install it unless you want to download more questions in addition to the 990 that the apps. Adding more questions is free.
This is good to know. Can the additional questions be added without wifi via iTunes ?
No, you have to connect via Wifi so that the app can get on GMAT Club forum but you can download them once a month or once a week or smth like that... is Wifi and issue for your location?
Where i am living Wifi is accessible only if you have one at residence. Wifi @ Work wouldnot allow external devices and public places still don't have wifi. My issue is solved - IPod touch have enough questions to keep me busy for a month or so. Thanks a lot BB, you were helpful and prompt.
It's easy to say you can't do it , you are not good enough. It's much harder to step in your shoes and achieve the improbable.
