I finished the HSC last year as a full time distance ed. student who actually studied for the hsc while living in QLD. Realistically i thought i could get a 80-85 UAI, but i did all the set work and even though it was difficult as i didn't have the access to lab for biology etc like others normal students, i still managed to get a UAI of 92.75 with no special consideration for being a dist. ed. student (as this is not allowed when you are classed as a professional athlete.)
Just thought i would let you know.
