So if you top externals (i.e. the actual HSC exam) you can top the state (if you don't come first in internals)?

Yeah (it's even theoretically possible to come first in neither externals nor internals, and still top the state).

So if you come 3rd in internals and 1st in externals (compared to school cohort) shouldn't your rank be second? Or does it depend on the difference in marks?

Depends on the marks (they clearly don't just average those ranks).

If you outscore 1st & 2nd in externals by more than they outscored you in internals your HSC marks will be higher than both of them.

What, how does this happen?

I was going to say it's simple, but I've been trying to come up with an example and it's quite hard. When you factor in ranks to determine internals, Girl C can never be higher than Girl A right? Since Girl C's external will always be girl A's internal mark??

e.g. 3 girls, girl A gets 98 internal, girl B gets 91 internal, girl C gets 90 internal. However in the externals, girl A gets 90, girl B gets 91, girl C gets 98.

Final HSC marks are: Girl A = 94, Girl B = 91, Girl C = 94.

Final HSC marks are: Girl A = 94, Girl B = 91, Girl C = 94.

$$\noindent Well yeah, suppose person A gets internal of $a$, with B and C getting $b$ and $c$ respectively for internal, and $a > b > c$. If in the externals these are reversed, then person A gets a HSC mark of $\frac{a+c}{2}$, B gets $b$, and C gets $\frac{c+a}{2}$. So C would always get the same final HSC mark as A. B would end up on top if and only if $b> \frac{a+c}{2}$ (i.e. $b$ is higher than the average of $a$ and $c$).$

$\noindent But note that the external performance influences how the internal marks are moderated, and therefore we wouldn't generally have this sort of exact ``reversed'' structure to the internal and external marks (especially with big mark gaps like in your numerical example, assuming a quite big cohort).$

$\noindent An easy example where third internal rank (out of a large cohort) could overtake first and second would be if first and second did poorly in the external HSC exam and third did well in that, and was close to first and second in internal marks. (Of course, to overtake someone ranked higher than you internally, it is necessary to beat them externally.)$

A's HSC mark is (90 + 98) / 2 = 94, agreed.
Whereas C's HSC mark is (98 + [90*moderation factor]) / 2 ; if the cohort's exam average is higher than their internal average the moderation factor is >1 and C's HSC > A's.

PS: The common saying that if you rank 3rd you get the 3rd highest exam mark (as your moderated internal mark) has been shown again & again to be incorrect.
