A section that meets twice a week:
All absences are considered "excused." Nevertheless, if you miss four class periods, you will likely miss enough information that it will impact your grade but there is no required penalty for missing four classes. If you miss five class periods (i.e., about 20% of the course) you will automatically get a letter grade drop, and if you miss six class periods, you cannot pass the course. If we do a graded piece of work in class, you cannot make up this work if you are not in attendance. If I teach a new technical skill in class, you are still expected to find a way to learn this skill on your own.
If you make a habit of arriving late or leaving early, I reserve the right to regard this habit as a "missed class."
