I plan to study Applied Mathematics. I am an international student. Between these universities, which one would be right one for me?
What is your GPA, ACT/SAT scores, Extracurricular activities, TOEFL score? What is your college budget since the California UC’s will be full price at $65K/year with little to no financial aid?
The one most likely to accept you and that you can afford.
If money not an object, apply to them all and then look for some far less selective schools as well. That’s the real challenge of college search.
