In the real GMAT will a question have the difficulty range of 500-600 /600-700 /700-800 as we see in MGMAT practice CATS and Questions Banks?
(or)
Will every Q be more fine grained to a level of difficulty in multiples of 50's and 10's? Some thing like 550-600/700-750 (or) 610-620/ 730-740 range?
Thanks
