You must be present during class to use your clicker. Using another person's clicker, or having someone use your clicker, or answering clicker questions via the mobile app when you are not present in class is academic dishonesty, and will be reported to the Office of Student Conduct & Community Standards. Penalties could include failure of the course.
We will not be able to deal with individual issues like excused absences, forgotten clickers, login issues, connectivity issues, dead batteries, etc.
To account for this we only require a threshold total of 75% of all possible points.
In other words, if you earned 75% of the available points, you received full credit for that portion of your grade.
