I use a variety of exams, depending on the subject matters. For certain classes, multiple choice and true/false makes the most sense but for a couple classes I teach I almost have to use essay exams. These classes are more on industry trends and opinions rather than concrete right or wrong answers, and an essay exam helps me evaluate how well students are truly comprehending the material and applying critical thinking. I know they take longer to grade, but I think they are far more accurate in assessing retention of material.
