Like I said, there are heaps of people who are good at the course but are not necessarily interested in all of it. Such people choose the course because they are able to gain good marks in it.
This has nothing to do with what I said - you originally raised the issue that MX2 was more difficult because the topics were fixed and thus students would be affected by their lack of interest. Making the argument that many are good at it anyway is self defeating - why raise the point of interest in the first place if you disagree with it?

Inversely, there are those who are very interested in the course but are hopeless at it. Even for those who are interested in Mathematics, there will be a few aspects of the course which do not interest them. They still take the course because the majority of the course is do-able and perhaps interesting. I mean, who would disregard a course if there was only a topic or two that didn't interest them? Just because you're interested in a course, doesn't mean you'll be good at it. Just because you're good at a course doesn't mean that you'll be interested in it.
If the majority of the course is interesting enough to students that they take it, then obviously the 'boringness' of the topics that you earlier cited would not be an issue.

The reason for that is because the vast majority of students who take the course tend to perform poorly across other courses.
Indeed. Doesn't change the fact that the majority of people would do poorly in Arabic - its an example to show that scaling is not an exact accounting of difficulty.

Scaling is dependent on the performance of the candidature and how they compare to a common statewide scale. In a course containing very talented students who perform well across other courses, the scaling would be high. In a course containing less able students who score poorly across other courses, the scaling would be low.
As you are most probably aware, scaling isn't an exact measure of difficulty. You are also no doubt aware that Extension courses aren't scaled that way at all. They are scaled as to how their candidates compare in the examination for the preceding course. To use Ext 2 English as an example, it is only scaled as compared to how its students perform in Ext 1 English opposed to those who only take 3 units of english, thus its 'lower' scaling only indicates that the performance levels of both 3 and 4 unit students in the Ext 1 English exam is rather similar. You'll find MusX undergoes the same process with an extremely similar scaling to Music 2.
