Follow-up Contact faculty members in whose research you were interested. This is either the easiest or the most difficult part of the whole process . It is usually a better decision to attend a program where there are a number of groups in which you are interested. Do this in conjunction with the department. Request letters of recommendation.
Some universities only accept complete applications.
This will be difficult for you unless you have taken GREs early. This is a VERY busy time. Don t look back. Don t second guess. Immerse yourself in your studies and new environment.
