Hey there samwr!
First of all congrats on the amazing ATAR, I hope you're going out and celebrating today/soon.
Your marks are awesome, but perhaps borderline even for a first round interview given how competitive med is getting nowadays.
So with second round interviews, it's... hard to say.
If you know what your school's estimate was, and your actual ATAR is higher, there is always a chance.
In any case, a second round interview offer is not something that anyone should stake too much of their hopes on. Just by nature of uncertainty, a second round interview is something that is nice to have, but not ideal to aim for.
I see that you got a WSU interview, which is super awesome, and I hope that that went well for you - how did you find it?
Congrats again and good luck for all in the future! Go celebrate! You have now finally ended your parley with the tyrannical Board of Studies :")
