大家好
我在申请U Mich的第9步，要填写class ranking
它要求If undergraduate institution is not in the United States of America,
please provide your class rank out of number of students in your class, and
information for the registrar Postal Address and Email Address.
请问这个registrar Postal Address and registrar Email Address该如何填写?

好像是学校注册组的地址信箱?

注册组实体地址及邮箱电子邮箱
