GAT in Year 11 - how much does it actually affect your ATAR?

I'm in Year 11 in Victoria and my school is treating the GAT like it's make or break, but I've also read it only affects your ATAR in very specific circumstances. I'm confused about when it actually matters versus when it's basically irrelevant to my final score.

From what I understand, the GAT gets used to verify internal assessments and can adjust your school-assessed coursework if there's a large discrepancy. So it doesn't directly add to your ATAR but can indirectly affect it. I scored 152 on a past paper practice and I'm not sure if that's solid or if I should be worried.

My school has us doing 3 hours of GAT prep each week for the next month, which feels like a lot given I also have SACs coming up in Maths Methods and English. I'd rather spend that time on SAC prep which will definitely affect my marks.

Anyone who's been through it - did the GAT actually affect your ATAR personally, or did it just happen and everyone forgot about it? Trying to calibrate how stressed to actually be here.

152 on the practice is solid - the median usually sits around 145 so you're above that. I wouldn't stress heavily about prep, just make sure you're familiar with the extended writing tasks so the format doesn't surprise you on the day.

Sat the GAT two years ago and it basically didn't affect my ATAR at all. For most students in most subjects it's invisible - the adjustment only kicks in when there's a significant discrepancy between GAT performance and school assessments.

Your school is partly cautious because the GAT affects their own reporting stats, not just your individual ATAR. Take that context into account when deciding how much prep time to actually give it versus your SACs.
