Ca someone explain to me why my friend got an ATAR in the 60s when all her marks were over 71? (Four Band 4s and one Band 5). Is this because of rankings?
the atar is NOT a mark. Its a ranking among everyone else in our year group. UAC looks at the the marks across all. the subjects and compares them and uses algorithms to scale the marks. This essentially works out how "difficult" a subject is compared to others, as it can be much easier or harder to get a certain mark in some subjects. For example, getting an 80 on ext. 2 maths is far more difficult than getting 80 in standard maths. From this, your scaled marks are calculated (we don't get these individually), and then compared to rank each student in order of achievement. \
So the actual numbers you get as marks from nesa do not directly translate to an atar. Your atar is only a rank, which is calculated by essentially comparing your marks against the rest of nsw to work out how many people did better than you and how many did worse
