This timer can be used while taking the gmat prep tests. This has a test log, which keeps track of how much time is spent on each of the question and allow to mark a question as in doubt.
Regarding donation, I would like the donation to be made to a charity of my choice. Thats all.
Could you please elaborate on what the timer is for? No phones or for that matter watches are allowed inside a GMAT center. So I am not sure how this would help in my preparation.
Also I am not sure if PG approves of using the site to share software and transfer of cash (as in a donation).
I have developed a GMAT Timer application on android. Interested people, please give it a test drive.
If you find this application useful, please consider a donation.
