考研学校用英语可以说成 "graduate school" 或 "postgraduate school"。如果你想表达“参加”这个考试，可以在前面加入动词 "take"，也就是 "take the postgraduate entrance examination" 或 "take the graduate school entrance examination"。此外，还可以使用 "take part in the entrance exams for postgraduate schools" 或 "take examinations for a graduate programme" 等表达方式。
