Section assignments are made by the registrar; please plan to attend your assigned section. If extraordinary circumstances make it impossible to attend the section you have been assigned, you may request a section reassignment by emailing 6004-staff@csail.mit.edu a request to be reassigned to a new recitation time.

You must have a non-zero score for each required lab and all on-line lab questions must be checked-off as a prerequisite for passing the course. A missing required lab (i.e., a lab with a score of 0) will result in a failing grade; incompletes will not be given for unfinished laboratory work.

The lab gets crowded just before an assignment is due so plan accordingly. The lab will be staffed by the course staff during the late afternoon and evening M through R, and during the afternoon on F.

The 6.004 lab is located in 32-083 and is open 24 hours a day, 7 days a week. An access code is required for entry; it will be given out during lecture. The lab offers 40 Linux-Athena workstations that can be used to complete the homework assignments. It is also possible to complete the assignments using your own computer: the lab software is written in Java and runs in Sun's Java 2 Standard Edition (J2SE) environment (see Courseware for details).

Late policy for labs: The on-line system will give you 50% of any points earned for submissions after the due date. So if your first submittal is late, you get 50% of the points. But if you submitted on-time for 15 points, and then late for 25 points, you'll get 20 points total for the lab. Note that points reported by JSim/BSim at check-in are for on-time submittals; you can check your on-line status page to see how many points count toward your total. This will be reported as "0" until you complete your checkoff meeting.

Late policy for checkoffs: The on-line system will allow only 50% of any points earned by your lab (including any late penalties you incurred) if you don't complete your checkoff before the checkoff deadline. So if you miss both the lab deadline and the checkoff deadline, you'll only get 25% of the total points.

To ensure everyone has a seat, please attend your assigned section on quiz days. If exceptional circumstances make it impossible to take a quiz at your assigned time, please contact your recitation instructor before the quiz to see if other arrangements can be made. Requests for make-ups after the quiz has been given are unlikely to be successful.

There is no final exam.

Once your combined score has been computed as explained above, here's how grades will be assigned:
