Scaling, aligning and UAIs (1 Viewer)

[~ ReNcH ~]

Seeing as scaling is performed independent of the aligning process, does that mean that it doesn't matter how much a particular exam is aligned up - your UAI could be just as high if you do exams that happen to have little aligning benefit?

After scaling, is everybody truly on a level playing field? For instance, I seem to notice that a lot of the people who do Physics get higher UAIs, whilst those who do Economics and Business Studies didn't get as high UAIs (although this is only concluded from posts made on these forums). Are any particular people disadvantaged in anyway by the scaling process?

Yes.

Yes.

The scaled means for Physics and Economics are both higher than that of Business Studies which indicates that Physics and Economics are, on average, taken by students who tend to do better in all their courses than the students taking Business Studies do in all their courses. It is no surprise that these students tend to have higher UAIs.

Theoretically, there is no reason for the students taking Physics to receive higher UAIs than those taking Economics.
