I'm a third year undergrad at Northwestern in math and statistics. I've tried asking advisors but haven't gotten any solid answers on requirements for the field, what to do to prepare, etc. I realize I'm looking at having to get a PhD, though I'm curious what schools and especially what programs I should be looking at (Math, Statistics, Applied Math, other). For now, I know I need to start looking at the GRE and other logistics, but also I need to make a decision on timeline. My best efforts have given me a 3.5 rounded up, and I'm just now doing my first research position, so I'm not really in great shape for applications, and I don't see it improving in the next year. I'm also don't think I'm emotionally ready for a PhD given some of the issues I've had in undergrad, so I'm considering taking a gap break between or working on a 5 year combined masters in applied math to transition from. Is my best option just applying now and going straight out of undergrad, or would a gap be beneficial to increase success on applications? I'm not shooting for Ivy League, but at least upper tier state schools. If I did gap, would it be beneficial to get the masters degree or to do some sort of global health volunteer work/any quantitative job in a different industry? Thanks for taking the time to answer this.
