Hi
VeritasPrepKarishmaWould you rate only last 1/3 of any edition of any OG revision as HARD?
Does the same logic goes true for quant and verbal review too?
In every OG, the harder questions are at the end of each section, and the easier questions are at the beginning. That's also true for the Quant and Verbal Review books. (The earliest OG I have is the 2012 edition, so it's possible that this wasn't always the case. However, it's true for all of the books since 2012.)
However, the arrangement of questions isn't perfect. I don't know how the GMAC decides what order to use, but I can think of a few cases where there's an easier question towards the end of a section, or a harder question towards the beginning.
Whether you'd call the last 1/3 'hard' or not depends on what 'hard' means to you. A GMAT question doesn't just have a single difficulty level. Instead, the GMAT uses data on which test-takers get the question right or wrong across the board. For instance, you might have Question X and Question Y. On Question X, 80% of 700-level test-takers get it right, but only 10% of 600-level test-takers get it right. On Question Y, 70% of 700-level test-takers get it right, but 40% of 600-level test-takers get it right. Which question is 'harder'? It's tough to say.
