VCAA says this:
"The GAT is used as part of a final check on external assessment scores. If there is a significant statistical difference between the final score for an external assessment and the score predicted by the GAT and school indicative grades, the external assessment will be assessed again by the chief assessor. Scores may go up or stay the same, but they will not go down as a result of this final check."
So it sounds important at least, but my teacher said dont stress abt it, as long as u give it a good go things should go fine 🙂)
