School policy currently prohibits extra credit. Whereas in the past I used a few extra credit questions to balance against potentially difficult questions or perhaps questionable questions within an exam. There are a few occasions where I might be testing difficult subject matter. I will create a 20 point quiz. Each question is worth 2 points, but there are fifteen questions on the quiz. No student can score higher than 20 points for the quiz. The extra questions provide an opportunity for students to make up for poor answers elsewhere within the quiz. In addition, students strive to answer all the questions.
