This is true but due to the fact Bio scaled like trash and English Adv tanks ATARS for fun, it would be unfair to give this poor kid false hope and make him think he get into a top tier uni for Med.
You are being stupid. We are saying that if he improves his marks he will increase to this but if he internal and external marks were the same he would get this mark. I am quite generous in my estimates....
Fact of the matter is that his English Adv, Maths 3u and Biology are gonna drag his ATAR down so I would say he will be closer to high 80s then low 90s.
The difficulty of internals is a big factor and at a low ranking school they are much easy than the HSC. Some low ranking schools give out 90s and then students all get B1s (no jk this happens)
