Did Project Academy make a General 2 solution? I can't find a link anywhere.
It is great that they did all 3 of the calculus ones - AFAIK the only ones to do so. But nobody has done all 4 yet.
That accolade for the first to do this online has for many years now been itute.com , a Victorian website specialising in VCE - but they publish HSC solutions too.
Unlike some others, they take their time with this - they take weeks, not hours. But given this, they nevertheless do still end up being the first to publish online complete solutions to all 4 papers. The ultimate HSC solutions hare and the tortoise story!
