How much difference can it make? What range of percentile will be consdiered competitive for an international applicant whose undergraduate major isn’t math? I have just taken it this month but only expect the percentile to be around 70%. I’m interested in the interdisciplinary application of math but due to many objective factors I only get a semester of Calculus, Linear Algebra, Statistics, Probability and Econometrics. I learned Abstract Algebra, Topology etc. by myself.
