<p>The upward trend will help you and many programs will focus primarily upon your math GPA and last 2 yrs’; however, the fact that you have a sub-3.0 GPA that could only be brought up to a 3.1-3.4 probably will hurt you. If you’re consistent from here on out, you’ll probably be okay for mid-tier schools, but I’m really not sure how competitive math Ph.D. programs are. Remember that it’s your classmates you’re competing with. Do you perceive that you are in the top 5-10%? If not, the fact is you may not be Ph.D. material.</p>
