6.864: Homeworks

[Main] | [General Information] | [Problem Sets]

  • Update: We have made a revision to the late policy for problem sets: we will give students 5 "free" days that can be used as they wish across the 4 problem sets. Specifically, we will not penalise the first 5 late days that a student incurs on problem sets. After that, the penalties posted on the problem sets will apply (e.g., 5 points per day late on the first problem set). The final (0 point) deadline will still apply; for example for pset 1 any solutions handed in after October 1st will get 0 points.
