There are two common methods used for uni admissions on combination of scores. Because the three components are on different scales (ATAR likely 9x to 99.95, UCAT from 2xxx to 3xxx, Interview from xx to yy who knows) they must be scale-standardised first.Does anyone know how Monash calculates the final scores by ATAR/UCAT/interview? I know they are weighed 1/3 1/3 1/3, but 1/3 what?
For example, 90%UCAT+ 99.95ATAR , and 99%UCAT + 99 ATAR, which one gets higher position if they have the same interview scores?
Speculative only but Monash is likely to use z-score. In this method they calculate the mean of each component, then your score is calculated as how far below or above this mean (a value between roughly -3 and +3). For example the mean ATAR of all interviewees is say 98.0, the lowest ATAR gets z-score -3, 98.0 gets z-score 0, 99.95 gets +3 (roughly), other ATARs are in between. Same for UCAT & Interview. The sum of these 3 z-scores is used for final ranking.
The other method is by individual ranks in each component. Say they interview 500 applicants, you get a rank from 1 to 500 in each of ATAR UCAT Interview. The sum of these 3 ranks is used for final ranking. We believe Adelaide uses this method.
