Early decision for Middleburg. My chances? (sorry for asking this question)

Hi, I am an international student in UWC Maastricht.
I got SAT but only 1220, essay 21/24 and that is the only sat I have had.
At school I take IB Philosophy HL, Chemistry HL, Langlit HL, Chinese SL, Spanish SL and Math SL and got 38/42 in total.
I focused on outdoor activity and for academics my most outstanding one is I represent Netherlands in the international Chinese competition and was given scholarship to study Chinese in my gap year.

I feel very unconfident as my sat is very low. Do I have any chance of getting into Middleburg early decision?
Thank you thank you so much
