Mr Young argument that he studied his notes and chapters for 18 hours before taking the exam and yet did not get good grade and thought he deserved a higher grade fails the standard of relevance. His argument is not important to the subject matter and lacks the existence to make the subject matter a fact. You can study for as long as you want, but there are other factors that determines good grades that Mr. Young did not consider, such as ability to retain information, intelligence level, and others.
