Ph.D. students may transfer a maximum of 5 regular courses (15 credit hours). You can transfer courses taken at other universities and apply them to your plan of study. For the course number, enter the number at the other institution, for example CSI 345 for a Computer Science and Information course. However, the course number cannot match the number of another course that you enter here (this is a limitation of this bubble-gum-duct tape software, not a graduate school restriction. It will be fixed in a future update). As an example, consider a transfer of CS 5714 for a class at another university, and you also took CS 5714 here at VT. To make the transfer course unique, add an X to the department name (e.g., CSx 5714 for the transfered course).
Remember that you must fill out a Credit Transfer Request Form (doc, pdf). Transfers must be approved before the PoS is approved.
