At GMAT Club, the difficulty level of a question is determined automatically once there are enough attempts via the Timer. It’s based on several parameters from users’ activity, such as the percentage of correct answers and the average time taken.

So while our categorization (Easy, Medium, Hard) generally lines up with the Official Guide’s classification, it’s not always identical because it reflects actual performance data from our pool of users.

does the difficulty KPI measure re-attempts ? this could hurt the real difficulty of harder problems.

Hi Borrat

As Bunuel mentioned difficulty changes based on timer attempts and difficulty, re-attempt counts as another attempt and yes that could hurt but the point is not difficulty. Let say there 100 person, one harder question was given to these 100 person,a mix of experience in critical reasoning thinking and novice, it may appear to easier to these experienced whereas those who have no idea this can be a diffcult one. Another scenario is timed environment, when the person is practicing untimed and he attempt this question correctly, this will appear easy to him but when similar type of question appeared in timed environment it may affect the thinking ability the person may not think As clearly because of timing pressure.

biggest throw off for option A should be the very strong wording "no reduction at all".
