62.5% is the ideal quiz score. Here’s why

 What is the optimum average score for a quiz? 100%? Not in my view. It is 62.5%, or a number close to that.

Time to update the Gap Analysis for your quizzes

Every quiz has, or should have a Gap Analysis template.

The same is true when you set a low-stakes assessment such as an end-of-topic quiz. Even if you Continue reading

Here is a question from our database, with one of its distractors (incorrect answers), and a feedback statement written by a student:
Question Distractor Feedback statement written by student
