Hey lizziesmum, depending on the candidature, she's looking at mid 80s. Ofcourse, considering the actual HSC exams make up 50% of the total aggregate score which is used to calculate the rank-based UAI, it's still very much in the hands of your daughter. But considering she's consistant (as in a slight improvement in the final exam as is expected with most HSC students) she'll safely be in the top 80%.
Also, lizziesmum, would you perhaps be interested in getting to better know a strapping young lad of 21 such as myself? Please do let me know.
Good luck to you and your daughter.
