Thanks for your help. These links are helpful. I've downloaded the spreadsheet and realized the questions are classified as 3 categories (easy, medium and hard). Could you please further clarify how these correspond to GMAT score level (i.e.: hard = 700+ level, medium = 600 -700 level, etc)? Thanks.
Yes, as supposedly the OG 12
is arranged in the order of difficulty (the further down the book the questions are, the harder they are). However, you should really only measure your progress with tests, not questions.
P.S. I am assuming you are timing yourself, right?
