As a faculty member in the humanities, I always pose essay questions in exams.  I prefer to pose more questions than students need to answer, and to give students the choice of which questions they would like to write about.  Right now I can post, say, 5 possible questions, each of which is worth 100 points, and instruct students to choose 3 to answer.  But Canvas assumes that if I post 5 questions, the grading scale will be 500 points.  Canvas does allow me to have it randomly select 3 out of 5 questions for any individual student to answer.  This will create a 300-point grading scale for the exam.  But I would like the students to be able to have that choice, and for Canvas to know this, so that the grading scale is correct.
