KAIST admissions

I am a high school graduate from Ethiopia. I am planning to apply to KAIST for fall 2019. I have 3.83 Gpa, 33 Act and 800 on sat math II and physics. I have taken part in a training program for outstanding students at a university, was a leader of the Christian students fellowship program and founder and leader of the chess club in my school. I have also participated in several voluntary activities. I really want to know my chances of being admitted because the application fee is a financial hardship for my family so I may decide not to apply.
