Hi Bunuel, can I check with you if this is a high 600+ question?


The difficulty level of a question is calculated automatically based on the timer stats from the users which attempted the question. So our stats say that it's 700+ level.

Hi Bunuel thank you for clarifying on how the question's difficulty level is derived. I have a better idea now on how questions are categorized.

I wanted to also ask if GMAC also uses something similar to determine the level of difficulty of their questions (I presume it's an algorithm of several variables, which time used to solve a question is one of the determining factors to categorize the difficulty of a question). But I guess time spent alone could be a good enough proxy already, and then if one answers the question correctly and also in an amount of time better than the majority of the distribution of timings, one would get a much better score than the others.

Thanks again for your clarification.
