Can someone help me better understand the difference between the "Program (PTCAS) GRE code" and the "University GRE code". The PTCAS page about this confused me and I just want to make sure I do everything right when I retake the GRE next Friday (took it last summer and didn't send scores). Can someone just walk me through the process of sending scores and what do do if you have more than 4 programs to send your scores to and if your program lists both "Program (PTCAS) GRE code" and the "University GRE code". Thanks in advance.
