You may rewrite any paper as many times as you like following these same guidelines. Your take home work will be collected, discussed or in some other way evaluated each class day. If you do not have your take home assignment, you will be counted absent for that day, as the take home assignments will feed directly into the in class work. You will also lose daily grade points, if the assignment carries a point total. They can, of course be longer.
Freewriting assignments have no specified length.
