I am an international student interested in philosophy ph.D program for 2021 admission. I am hereby posting to ask a question related to TOEFL report. On the one hand, many school says that, for GRE and TOEFL reporting, only the institutional code but not department code must be entered (for example, UNC. https://gradschool.unc.edu/admissions/instructions.html). On the other hand, TOEFL website forces me to enter whatever department code. Among those seen on the department code list are 20 (philosophy) and 99 (for any other department not listed). Which should I choose, for the score to be properly reported? Should I mail and ask this question to each school that says like that?
