Right I imagine the grades for exam 9 will be clustered around a point or two. And that’s why my earlier question of will the CAS be inclined to make the pass mark above or below the cluster is important.
If everyone did virtually the same and messed up the same few questions/didn’t know how to do a couple of questions. Then it all comes down to the clustering and how you did on the IQ.
I really think the IQ is a terrible way to differentiate candidates.
