The answer is No and Yes or, "It depends."
There are no extra-credit opportunities for individual students. No points will be awarded for work outside the course's scope.
There is, however, an opportunity for the Teams to earn extra-credit points by entering the "Elevator Pitch" competition during the Tenth Week. To learn more, check out the "Elevator Pitch/Extra-Credit Championships" category.
Another question that may be asked even more frequently is, "Can I make up a quiz or examination that I missed?"
The answer is Probably Not.
The general rule is the Course's schedule will be strictly enforced. Exceptions may be granted but only for documented circumstances beyond the student's control that prevented the student from being present for the quiz or examination.
Note that exceptions are just that - exceptions. In most instances, you won't get a chance to make up a missed quiz or examination. You may - there's no guaranty - get to make up a quiz or examination if (1) you were absent for a reason that you couldn't anticipate or control and (2) the circumstances that caused the absence are satisfactorily documented. An example might be hospitalization. In such a situation, you would be required to produce written proof that you were, in fact, hospitalized.
