听力原文：Xavier: Hi Olga. Did you find that information about grade appeals? I found the information about student records. Olga: Hi Xavier. Yes, I got it. Let's have a look through together and see what we can find. You start. Xavier: OK. Educational records, including all student records, are maintained by the Office of Records in room A167. Student Q21 records are maintained in a manner that protects the privacy of students and provides eligible people access to the information recorded. Olga: I heard something about public information. This can be given to certain people at the university without a student's permission. Xavier: Ah, yes. That must be public directory information.

A grade appeal refers to any of the following: the assignment of a grade to a particular student on some basis other than academic or behavioural Q26 performance in the course; 6 the assignment of a grade to a particular student by using more exacting or demanding standards than were applied to other students in that course; the assignment of a grade by a substantial departure from the instructor's previously announced or written standards. Xavier: That seems reasonable. Olga: Students have a right to a grade review to correct an erroneous grade and to a grade appeal as a remedy for an unfair grade in a course. Even before the review, the student must contact the instructor by midterm of the following term and Q27 request a review and an accounting of how the grade was determined. If the student is satisfied with the response, the procedure ends. Xavier: So, there's no way t
