D, who is a rising sophomore has always had the goal of PhD. She is a Math major who will double in either CS or Chem, with the other being a minor. Of course, we both know she might change her mind between now and her final year but what should she be doing now to line herself up for that goal?
End of year GPA is 3.95 and she is doing a 10-week faculty/student collaborative research project this summer to ensure that she enjoys doing research. Other than doing research and an internship and maintaining a GPA over 3.5, are there particular things she should be focusing on?
