simple process of applying online and getting the position. You get class credit that can be used towards increasing your grade point average and is helpful in teaching the students of the class.

pass two exams(common and area tests). tests are held separately. Different track requires different area exams. I was applying for computational applied mathematics track. So, the area exam is based on numerical analysis skill and coding skill. next, I join one professor's research group and took a small project. when the project was finished, I was recruited. It's not hard if you prepare it. Also, at that time, they have extra funding and need student to contribute the coding skill to the open project.
