The binomial expansion is actually used when distributing IP addresses, economic predictions and infrastructure in engineering and theres many more applications.
Really depends on you and your cohort. Good thing about low ranked schools is they can easily fluctuate, so who knows I believe you can squeeze the 80s.
You assessment mark will be a bit below the highest because its about the gaps between students so in the case you are much closer to the first student. Its like a rubber band, you put dots on the band then stretch or shrink it depending on the external marks comparing to the internal marks.
Tbh, I liked AOS because I always felt paper 2 was harder with the 3 essays otherwise it's not even English its just Essay studies. But seriously, the entire subject is useless anyways.
LOL I did it last year for my HSC. I felt it was easy because we had much harder questions in our school exams so really schools should definitely place emphasise on hard questions to make the HSC feel relatively easier.
