KAIST International Graduate Admission

Hi, I finished my bachelor degree in Chemical Engineering Department, Bandung Institute of Technology, Indonesia with GPA 3.01/4.0. Since then, I’ve worked as process engineer for almost three years. I have relatively average GRE score of 313, but a pretty good IELTS score of 8.0. Realistically, how high or low is my chance to be admitted in KAIST Graduate School? I have applied anyway so I just have to prepare for the worst, like, applying another university. Thanks!
