Hi
bb,
is there any way GMATClub could introduce filters by the rate by which a question was answered correctly / incorrectly?
One can filter for hard questions, but then, there is a lot of variance in how many people got hard questions correct or wrong. For example, a hard question can have 80% correct solutions, another one only 15%.
An example for implementation would be that one can filter hard questions by what percentile of people got them wrong or right (i.e. 50 percentile, 10 percentile etc).
Why would that be nice to have?
It would allow for more granular studying. Some people might be quite comfortable with most hard questions, and look for harder tasks to improve, but will have difficulties identifying the ones which only few people got right. Are these necessarily harder than the hard questions in general? No, but again, that depends on how hard is defined. IMO, mostly, the hard questions with high incorrect answer percentages usually are harder than ones with high success percentages
Thanks
