Final Exam
Open notes, open homework
Here are two sample finals

Submission policy.  For the programming assignments (assignments #1, #2, and #3), you must submit your solutions electronically via the Dropbox submission system. You will need to type your Princeton netID and password for authentication. Be sure to include your name and login at the top of every file you submit. Also be sure to click the Check All Submitted Files button to make sure that you have submitted all of the required files and that they compile cleanly. If you do not follow these directions, you will lose a substantial number of points.

You can resubmit and unsubmit files as needed up until the submission deadline. However, once the submission deadline passes, you should not resubmit or unsubmit files: if you wish to submit an assignment late, be sure that your submission directory is empty from the deadline until you are ready to submit all of your files for that assignment. Any files that have been submitted at grading time will be graded as is.

Lateness policy.   Homework will be due at 11:59 pm. Late homework will lose 10% of its value for every day of lateness. Homework more than seven days late will not be accepted.

No homework extensions will be given except in extraordinary circumstances (such as documented illness), and then only if the official university procedures are followed.

Collaboration policy.   Unless the assignment explicitly states otherwise, you may not collaborate with other students on the homework. (Of course, if it is a group assignment, you should collaborate within your group!) If you make use of outside sources, you should disclose that fact and cite the sources, as you would in any scholarly work.

Important note.   Please do not publish solutions to programming assignments in a way that could compromise their utility as pedagogical tools. At Princeton, this is a violation of the basic rights, rules and responsibilities of members of the university community.
