Assignments
Grading: Each assignment is worth 11% of your final grade. Out of the 11%, 2% is for your written algorithm, and 9% for the implementation.

Late Policy: All the assignments due at 11:59pm on Monday (the night before the Tuesday lecture). Exceptions will be noted on the assignment handout. The algorithm worksheets are due at noon on Fridays of the week when the assignment is handed out. Assignments that are turned in late will receive a 0. The rationale for strict deadline is that the assignments are built on top of each other (e.g. you cannot complete assignment 4 without completing assignment 3). So completing each assignment in time is essential to the success of the next assignment. If you have an extraordinary circumstance, you should contact the instructor or the TA as soon as possible and obtain written approval.

In-Class Labs
Grading: There are 8 in-class labs, each is worth 3% of your final grade. Note that Lab0 is not for credit, but getting WebGL to run is essential for the rest of your course work.

Late Policy: All in-class labs must be completed by the start of the next in-class lab (usually 1 week). The lab will be checked in person by the TA or the instructor during class. There is no late policy for in-class labs. You will not receive partial credit for turning in a late lab.

Final Project
Grading: Your final project will be graded in-person during the final exam period.

Late Policy: There is no late policy for the final project. You will receive a 0 if your final project isn't working by the demo day.
