So, just to be clear, if the professor writes an exam which is harder than anticipated, you are ok with adding points to correct for the difficulty of the exam and prop up student grade to a desired distribution? Or you believe all the students should fail? But if the exam was a little easier than intended (which rarely happens), it’s no longer ok to try to correct for the difficulty of the exam? Those students just lucked out and all should get As and next semester or next year, the grading will be back to normal?
