When a law student in Hawaii failed torts - the study of wrongful acts that lead to lawsuits - he sued the school. One imagines his professor must question his life decisions. You spend your life teaching people how to sue. Here you go.
The student claims he should have the right to read everyone else's test to see for himself if he really fell below the curve. He's not the first law student to sue a law school for a bad grade.
The Texas Southern University School of Law was sued a few years ago by students who got Ds. The Supreme Court has looked at grading cases, which have also been filed against colleges and even high schools and has said that it will generally not second guess a school's decision unless it can be demonstrated that those at the school did not exercise professional judgment.
The Texas law students lost their case, as will be the likely outcome for the Hawaiian law student, who is also asking the court make the dean give him a recommendation.
Here's a recommendation: don't sue the school for a bad grade. You won't win.
