Policy for lateness:
Up to 3 hours late: ½ grade penalty (e.g., A reduced to A-);
3 – 6 hours late: 1 full grade penalty (e.g., A reduced to B);
6 – 12 hours late 2 full grade penalty (e.g., A reduced to C);
12 – 24 hours late 3 full grade penalty (e.g., A reduced to D);
> 24 hours late: paper will not be accepte
