5 late days are allowed in the semester.
Late days can be used for Homework problems ONLY.
You may use them as you wish e.g. use all 5 on one homework, or use 1 for each homework, or use none, but late days cannot be used after the solutions have been posted on the class website! In some cases, it might be only two days after the deadline.
No late days are allowed for project and paper presentations, exams, in class quizzes, and final project report!
You will only need to submit 4 out of the 5 homework assignments. If you submit all 5, the best 4 will count in your final grade.
