Lol... this is the craziest thing i have heard about gmat prep. 20 hours a day is not sustainable for more than 2-3 days.... You will do permanent damage to your health by only sleeping 4 hours a day for 365 days.... 20+ hours a day is worse than studying 3-4 hours a day 5 days a week for 6 months which could get you 700.
Whats the point of even getting 800? You could just as easily get into most schools with a 700+ score.
