What's my chance to get into JHU BME(ED)?

I’m an international applicant.
Stats:
SAT: RW720M800(2019.12) – would be higher next time
GPA: Predicted 4.38/4.40 by ED. Predicted Rank 5/100. From a highly competitive school locally
SAT2: Math II 800. Plan to take Bio M and Chem, should be 800x2
AP: Cal BC 5 , Phy 1 5. About to take Lang, Bio, Chem, Stat, Phy C Mech, four of which should be 5 at least.
Awards&Activities: Some Chem and Bio Olympiad Golden and Silver medals. Won’t weight much I think. And a paper on Chem.

Am I competitive regarding stats?

You are definitely a competitive applicant. JHU admits a large portion of the incoming class through ED, so I would definitely recommend applying ED if you want the highest chance of being accepted - I know many international students who were accepted ED, and your stats are very similar to theirs, potentially higher.

wait, TWO international science olympiad medals???
