2025 amc is tomorrow in australia. maybe solutions can go up here later but it is officially a 3-day thing.

unfortunately some other countries do it much later than australia so it could be a while before u see online copies of the papers.

the 3-day option applies in other countries too so this is why they had on the bottom of the paper:
