the penalty of late submission

As some of you might concern, the penalty of late submission is as follow:
Late submissions will be scored using a graded approach:
Less than 1 day late: reduce the score by 15%
For each additional day, up to 3 days: reduce the score by further 15%
More than 3 days late: not accepted.


It's a good idea if you submit the unfinished version in time and then submit another version. We will give you the maximum grade for the first one and then add credits for second one with the penalty.
