Multiple No Choice
I had a professor in college who would give partial credit on multiple choice questions. It wasn’t something like, show your work and get partial credit, it was circle the correct answer and cross out the wrong answers.
For a question with 4 answers, each wrong answer crossed out was worth 25%. I didn’t try it because they were pretty easy tests anyway, but one of my friends tried just crossing out every answer. He got 75% for crossing out all of the wrong answers correctly.
