There is/ was a kid at my school, he is the dux. I have seen rankings of my school in the top 30. What do you think his atar will be?

Chemistry (he did one year early) - 1/30 (state rank: 3, the person ranked 2 in my year was ranked 6th in the state)
Ancient History - 1/60 (very very very likely state rankings + 100% in trial)
Physics - 1/45 (likely state rank)
English Advanced - 1/160
English Ext. 1 - 1/80
Mathematics Ext. 1 - 1/50
Mathematics Ext. 2 - 2/21 (barley any difference between top 3)
HE ALSO GOT 100 IN HIS UMAT!!

I reckon 99.7+, but I think he has a decent chance of going all the way to 99.95.
