Well it depends if they use it before or after the ucat.
Applicants with the same entry score
There may be more applicants with the same ATAR or selection rank than there are places available in a program.
In these circumstances, we choose between applicants by using more detailed measures within each ATAR or selection rank. These measures might include:
- the aggregate of the first 4 section scores in the University Clinical Aptitude Test (UCAT) (for entry into certain programs)
- Section 5 and section 1 UCAT scores (where applicants have the same UCAT aggregate score)
- further breakdown of an applicant's GPA (for selection ranks based on tertiary study)
- applicants who achieve an ATAR or selection rank of 99.00 or above without adjustments will be considered before applicants who achieve a selection rank of 99.00 or above after adjustments are added.
This^ reads quite clear to me the raw vs boosted rank is only a 3rd-level tie breaker if needed, probably 1 in a million cases.
I understand UQ Dent selection process is : you must meet Rank 99 (bonus included if applicable, otherwise what's the point of giving the bonus), then differentiate on UCAT sections 1-4, then tie break by section 5 & 1 / GPA / raw vs boosted on the last few places.
