    Application of series and sequences question

    Ok let's take note of this firstly: 0.7 = (1+(0.7/100)) = 1.007 0.8 = 1.008 (similarly) 5 years = 60 months 12-5 = 7 years = 84 months Now we will have two series Our First Series: A1 = 50(1.007) A2 = 50(1.007)^2 + 50(1.007) A3 = 50(1.007)^3 + 50(1.007)^2 + 50(1.007) . . . A60 = 50(1.007)^60 +...

    How do the UAC preferences work?

    Do you have to accept your offer for your first preference? If you reject it will you get an offer from your next preference? Also are you able to change course preferences after you receive your ATAR? I heard you can but I can't find anything confirming this. Thanks for the reply btw.
