This question already has an answer here:
I'm currently finishing up my last year of study as an undergraduate mathematics major at a top 2 public school. I've been interested in getting a phD in mathematics for some time now, but my GPA and work in some classes in my 1st and 2nd years leaves a lot to be desired. Let's just say I got pretty bad grades in important classes. Since then, I've worked my but off and currently have around a 3.3 GPA.
Luckily, I was accepted into a Statistics/Computer Science related Masters program. In this program, I will have the opportunity to take electives and plan to take some higher level math classes.
My question is, will doing very well in my masters program next year override my poor performance as an undergrad? Also, should I be really trying to get a research position this summer?
