so theoretically you would need an assessment mark of minimum 80, which you would then need an 100 for your examination mark (which I know is unrealstic) to b6.
Assuming that your rank isn't terrible, like top 20 but your school gets around 5-10 b6s a year. Would a b6 still be possible with an externals comeback
What happens if an average student ranked around middle of their cohort, in an average school scores 100 on their externals test. Would it boost their atar by an insane amount since externals is still 50% of their HSC.
