Well, i have not taken the GMAT yet but, while taking a practice test, i was could focus because of something that i possess within myself. I'm very curious about the next question when i have solved one and when i am about to click on the confirm button. So when i confirm the answer, and when the next question appears due to my curiosity i totally am able to focus on the question. Its like the newly released movie. If my fav. actor's movie is going to be released i become curious and when i see the movie i totally forget about the world for the 1 1/2 hours!!!! But if i go to a movie which i dont even care, then i loose focus and my mind starts wandering!!!
I dont know how much this going to help anybody but just felt like writing!!
