Correct question type sorting -- but the source must be OFFICIAL questions (not all sources). I find it hard to believe there are only 4 655-705 permutation/combination questions on GMAT club from official resources.
You will need to use your critical reasoning skills to resolve the paradox 😇
error-log-for-gmat-official-guide-445984.htmlYou can find the
error log for the official guide with the difficulty of every question identified.
The reason you’re not finding for mutation and combination questions of a hard difficulty in the official guide is that they’re not many of them in that book and there are not many of hard questions either.
This is the reason there are many prep companies creating questions and resources because the official guide does not provide enough. If you want to use only official questions - got the four questions. good luck. 🤷♂️
