What's the point of the school assessment and external assessment then if there is an equal weighting of 50% for each? I heard this one girl at ruse came third internally but smashed externals and came first in the state for bio. Was this because her internals were completely redundant or what?

If you're a cohort of 1 student, ultimately there IS no point.
Whereas if you're in a cohort of at least 3, the raw marks still don't matter. It is the relative mark differences as Jamon would've said that matters.
I.e. Cohort one has marks 90, 80, 70 internally, whereas cohort two has marks 90, 75, 70. Moderation will impact DIFFERENTLY
Cohort three has marks 90, 80, 70 internally, whereas cohort four has marks 80, 70, 60. Moderation will basically do the SAME thing to BOTH cohorts

Internal RANK matters, as does relative placement within the cohort. But the value of the mark itself does not. The purpose of this is that schools will assess differently, but as long as all students in the same school get the same tasks, the ranks can be trusted, even if the marks can't be 🏻 I suppose we do internal assessments because basing absolutely everything on a single exam would be really mean, so they give you a chance to influence it

Would there be a moderation effect on a cohort with only 2 students?
So if your internal average mark was like 60 and your external mark was 95 (and you were first in the cohort and the exams were more difficult than the HSC, the BOSTES would do the average of the two exams and scale it up to like 90 (I'm assuming)
Wouldn't the same thing apply in a cohort of 1-2 students?

I'm fairly positive a cohort of 2 works just like a cohort of 1 yes.

Student A get 60 internally, 90 externally
Student B gets 55 internally, 83 externally
Very likely, as an overall mark, student A will get 90 for internal and 90 for external, whilst student B will get 83 for internal and 83 for external (with some very minor modification).
Student A gets 60 internally, 83 externally
Student B gets 55 internally, 90 externally
The marks will then become more difficult to quantify, but Student A will receive a mark of 83 for their external mark, and slightly below 90 for their internal mark. Conversely, Student B will get 90 for their external mark, but slightly above 83 for their internal mark. You take your rank, find that rank in the cohort for the external exam, and that is approximately your internal mark. It works exactly the same for a cohort of 1, 2, 80 or 140.
