Studying in a South Korean University

Hello, I plan to study in a South Korean University, my two option at the moment are: Kaist and Yonsei Underwood international College, because both of them offer Business bachelor degrees taught in English, with that being said would like to know if it would be possible for me to be accepted in those universities as an international applicant based on the information below.

Some information:
My Higschool grades into the American Gpa it will be something a bit over 2.71 (b-)
I study in a good University here in Brazil and my accumulative grade is 9.0 ( the maximum is 10.0)
I am learning German and I will take the Testdaf (test to show your level in German) next year
I know Portuguese ( my native Languague), English (My toefl ibt score was 110) and Spanish advanced
I have been working for 1 year now
I will start learning Korean next year.

Is there any other good like Yonsei and Kaist, in South Korea where classes are taught in English that you can recomend me?
