Grade appeals

I don't understand what you are trying to appeal. Are you appealing a grade because you didn't understand the format of the questions? If that is your basis, then you will not succeed unless the entire class did poorly on the tests. The time to appeal individual questions on a test would have been immediately after the test. You would have to defend your answer by showing that the correct answer on the test was different than your textbook and you chose your answer based on the textbook. Since you are 1.5% below passing, appealing that many questions successfully is very unlikely. What is your expectation? Do you want them to automatically give you a passing grade? How would that be fair to other students that also failed the class, do they automatically pass also?

If you are appealing to retake the class, then you need a hardship circumstance that prevented you from being successful. Examples of hardships would be severely ill during the semester in which you missed numerous days of class; death of a spouse, sibling, parent; house fire in which you were homeless. All of those would have been well known to the school and your appeal to retake the class would be successful. Not understanding the questions is not an appealable circumstance.
