Thank you!
Could you elaborate on what the BSSS number is by the way, because a few people may have the same name and without the the UAC number, how could they be sure who's who?
The UAC number just refers to your application not to your UAI. You should have been given a BSSS number when you started primary school (if you did any schooling in NSW you should have one - although it may have been called something else until high school) and it may or may not have been your student ID. It will be on your Year 12 Certificate, and possibly your year 10 and school reports.
Failing that it is extremely unlikely that anyone will have the same first, middle and last name (you have to supply your full legal name) as well as the same date of birth and attended the same high school, this is all information you give when applying to UAC and from this they access your results.
