Communicate with your professor. Most colleges and universities require students to try to come to an agreement with the professor who graded them before taking an appeal up with the university. Maintain a professional, respectful and calm attitude when talking with your professor. Reference his syllabus and make a case for why you deserve a better grade instead of just demanding a changed grade.
Initiate the appeal within 30 days of your final examination for the course. Although some colleges offer an extended timeline for grade appeals, this 30 day limit is typical.
File a petition with the dean of your college. Many schools have forms that must be completed, while others allow you to simply send a letter to the dean. Make sure to include the reasons you believe you deserve a better grade, such as syllabus entries and projects you completed for the course that you believe were graded unfairly.
Assemble all relevant course material. Bring in examples of tests, essays and projects you completed when you are scheduled to present your case to the panel. You will need to bring evidence to support why you believe you were graded unfairly, such as syllabus statements and information from course textbooks.
