What does Avg Diff Score exactly mean on MGMAT CAT tests?

Question

Just a quick qs, what do the two scores mean? Avg Diff Incorrect means that, that's the average question level of all the questions I got incorrect and the same for Avg Diff Correct?

Yes, that's what it should be, although I'm not sure about "Avg Diff Score" (the term in the title of this topic).

Yes, that's what it means. Those numbers are useful when you do better in one category than in another (for instance, if you get 80% of the Geometry questions right but only 40% of the Algebra questions right.) If the average difficulty for Algebra questions is higher than the average difficulty for Geometry questions, it may just mean you were unlucky and got harder questions in that category. In that case, you wouldn't worry as much about getting fewer Algebra questions right. On the other hand, if the Algebra questions were actually easier,  and  you missed more of them, you'd want to look at that very seriously as a weakness.
