With my work experience at Teradata and my Undergrad Math courses, I have strong Mathematics, Coding and Data Wrangling/Cleansing background.
My only concern is my UG percentage. Although it is a first class, I'm not sure how it would fare in comparison with applicants from other universities. I used the Eller College GPA Calculator and it showed my GPA to be 3.6/4.0

I request seniors to evaluate my profile and the choices I have made.
Looking at my overall profile, do you suggest I aim for more ambitious universities or should I apply to more safe universities?
