For the proposal and the 4 assignments, we allow a maximum of 5 days' late submission. For the final design, we allow a maximum of a week’s (7 days’) late submission. And for online discussions and the peer review, we allow a maximum of 3 days late submission. If you submit your work on time, you are going to get a 1 point reward for each assignment, and a 2 point reward for the final design. If you do not submit your work within the time allowed for late submission, one point will be deducted every day (subject to Beijing time) until the deduction is completed.
