Here is what their site says:
Applicants for all graduate programs in music are required to take entrance exams in the areas of music theory (aural and written) and music history. The purpose of these exams is to discern the applicant's readiness to pursue graduate work in music. Applicants must demonstrate a minimum level of skills and knowledge on the entrance exams in order to be accepted into the program. For students who are accepted, the exams indicate whether they need review classes in specific areas before entering into graduate-level course work. Admission of students who need review classes will be provisional until these requirements have been completed, which should be before the student has accumulated 12 graduate credit hours. Applicants in some areas of specialization (indicated below) are also required to take an additional exam in the proposed area. All applicants should take the exams seriously and attempt to do their best work. Because the exams are also a factor in admissions decisions, applicants should not consider the intention of taking review classes as an alternative for satisfactory performance on the exam.
Regular Entrance Examinations are scheduled on 4 dates per year at the School of Music. Additional dates may be scheduled to accommodate various programs. The dates usually fall in these months (but may vary year to year):
November
January/February
February/March
June (Please note that most programs will have made all their decisions regarding admission and financial assistance well before June. You are strongly encouraged to take the exams on one of the earlier dates to be considered for Fall admission..)
Musicology, applicants for the Ph.D. degree
In this exam, students are given a musical element and/or genre and asked to trace it through several epochs of the history of music. Students will also be asked to discuss one or more specialized topics in areas including music research and bibliography, music in vernacular and cultivated traditions, music and culture, and Western idioms and styles.
CONFIRMATION OF EXAM REGISTRATIONS: Applicants who have registered for the graduate entrance exams will receive a confirmation email a day or two before the exam date when we have the details (room, proctor, etc.) and a complete list of those who have registered for that date. We are not able to supply detailed information before that time, but scheduled exams generally begin at 9:00am and are finished between noon and 1:00pm. If you need to change your exam date, please resubmit the exam request form.
Please plan to arrive at least 15 minutes prior to the beginning of the exam in order to be settled and ready to begin on time. Location (usually in the Fine Arts Building or Fine Arts Library) will be provided in a confirmation email a day or two before the exam.
Students wishing to be considered for Fellowships are advised to take the exam in November, but may be eligible for consideration if they complete it before the end of January. Students wishing to be considered for TA must take it no later than March. Students may audition the same day if they take the exam in February or March.
It still seems super weird to me though. I will call them tomorrow just to find out if you can take it remotely. Otherwise, it might not be an option....
Anyway, I hope I didn't scare people from this thread! Please feel free to talk about other schools and plans you have this summer to prepare for application season!
