With two days left of VCE exams, the head of Victoria's Curriculum and Assessment Authority has stepped down after it was revealed last week that with a little detective work, students could access some of their exam questions ahead of time. Last week, education minister Ben Carroll said the questions had been re-written so no student would be disadvantaged. But today, he revealed some questions could have been impacted by the VCAA's error. This is how they plan to deal with their stuff up.
