Hey guys/gals, I have a quick question. How are GMAT questions rated in terms of difficulty? Is it a "pre-determined" level (easy, medium, hard question) that GMAC ranks the question, or is the question difficulty based on the percentage of how many people get it right?
For example, questions from question pack 1 and 2 from the MBA.com store and OG question bank from Wiley's website have questions that are already pre-determined in difficulty; the difficulty assigned can be vastly different from the difficulty levels produced by GMATclub's timer for the same question.
-A "hard" question from the question packs can be rated as "easy" on GMATclub.
And does this apply to questions during the actual GMAT exam?
