Adjust your work schedule to accommodate this requirement. If your work schedule changes, drop the class. If illness prevents you from doing the work, drop the class. If your grandmother's illness prevents you from doing the work, drop the class. I will expect verifiable excuses for illness, death and all other absences for lenience.
Broken cameras are no excuse.
Borrowed, plastic, instant or pinhole cameras can be substituted in this instance. If this is a problem, drop the class. I have a great deal of experience working with students in photography. I have seen many photographs up close and in person. I can and do make judgments that are based on very subjective criteria.
