Homework consists of programming and written assignments. There will be no midterm nor final but instead an extensive (research-oriented) final project.

The grading breakdown is roughly as follows:

Component | Weight |
---|---|

Homework | 40% |

Attendance | 10% |

Final Project | 50% |

Blackboard will be used only to report grades.
Up-to-date information on other aspects of the course
(assignment due dates, etc.) will be posted on this website,
so check back frequently!

**Assignments Key:**

Unless otherwise noted, assignments are due at 11:59pm.

- Homeworks later than 24 hours, or from students who have already turned in 2 late homeworks, will receive 0 points.

Instructor/GA | Noninstructor (e.g., Another Student) | |

However, **under no circumstances** are you permitted
to share or directly copy code or other written homework material,
except with course instructors.
If I discover that you've cheated on an
assignment, you'll get an automatic 0 along with an immediate
referral to the
Office of Community Standards, which will likely
take disciplinary action against you.
Remember: homework is there to give *you* practice in
the new ideas and techniques covered by the course; it does you no
good if you don't engage!

In general, students in EECS courses such as this one must adhere to the Russ College of Engineering and Technology Honor Code, and to the OU Student Code of Conduct. If you haven't ever read these documents, please do so.
