Do you advise me to offer mediation, or pay a sum of money, or not care and fail the year, regarding the failing grade the doctor gave me for my exam?

If a student makes a mistake in answering a specific question, it is not permissible for him to pay money or use intercession to succeed, because intercession in this case is forbidden, and paying money is bribery. However, if the meaning of the question is not clear, according to the agreement of most students, then the student has the right to refer the matter to the university official for consideration.
