what about rankings?
Well I mean, ok. To give you a better explanation of my logic.
Firstly, SACs are not even worth that much in Methods. They're worth, what, 33% or something like that? (Might be slightly different if my memory is whacked out).
So, even if you copped like a B+ for SACs, and full marked both exams - that's an easy 40+. There've been people on ATAR Notes who've got a 40+ in Further/Methods/Spesh with a B+ before, because they smashed the other graded assessments.
Now, that's with a B+. With YOUR SACs. You've said there's a super high top end, and that the school is pretty decent, AND SACs are STILL not over - there's room for you to finish ranked in the top 10, or even top 5, theoretically. So like, even if you finished rank 17, you could still get an A for SACs but your question was "is this the end", and, if you could still finish in the top 10 and still score very well in the exams then... it's just categorically not the end haha. No? It's just not the end until the exams are over. If you've only done 17% of the subject... seems natural to think that if you dominated the other 87% you could still great a really good score, no?
