im not exactly sure about the percentage cutoffs for each level, but ik smo that did the entry into y7 test for ngo and she got high 80’s( I think around 87/88) and got into the advanced class. However, a hurlstone focus class opened it so after a while she joined that. After around 1.5 years she got asked to join the accelerated class so don’t sweat it if u cant make it into the accelerated/specialist class straight away. Doing well in the exams and doing the hw consistently will allow u to move up levels. Anyways that should give u an idea of what is expected, I think for advanced the minimum needed in the entrance exam is probably 80-85 and for accelerated maybe 95? You can ring them up and ask them what the cutoff marks are. If your concerned regarding the topics in the exams maybe you could ask them that too, I’m not sure whether they’ll tell u tho.
