1) 6.08 Grade

Your grade in 6.08 will be the weighted average of the following component grades:

Tutor Exercises20%
Design Exercises10%
Peer grading5%
Final Project35%

1.1) Midterm Exams

The midterm exam will be given in the evening (7:30-9:30pm) of Tuesday April 9th. The exam will cover all materials contained in lectures, online tutor problems, and labs, up to the date of the exam.

If you must miss an exam because of a direct conflict with an MIT class or MIT extracurricular activity, please contact your section instructor, and we will figure out a plan for making up the exam. Other than direct conflicts with other MIT classes and MIT extracurricular activities, alternative arrangements for exams will only be made for personal or medical issues, with written support from S^3.

1.2) Lab and Exercise Completion Grades

Lab and tutor exercise grades are based on completion. We expect that students should be able to arrive at the correct answer to these questions after some work, and so online questions will be considered completed if you arrived at the correct answer, regardless of the number of submissions you used.

1.3) Additional Completion Criteria

A central element of 6.08 is the open-ended design problems found in the lab, Design exercises, and final project, as well as the rigorous analytical nature of the midterm exam. Thus, for every lab you have not fully completed at the end of the semester, a half-letter grade will be subtracted from final grade. Missing the exam without an excuse will also result in a half-letter grade subtraction (in addition to the 0 on the exam).

1.4) Design exercises

For every set of homework exercises, we will generally have about two or more open-ended Design exercises, which ask for implementing a neat mini-project will little scaffolding from the staff. These Design Exercises serve as preparation for the final project and are meant to increase your confidence in your ability to solve open-ended problems. Over the course of the term, each student can complete as many design exercises as they want. Each Design exercise is worth 2.5% of your final grade, and is graded by succesful demo and code submission, with partial credit a possibility, however grading is very discrete. 10% of the overall class grade comes from design exercises, so the points gained from them will max out at that (you cannot do 5 design exercises perfectly and get bonus points or will just cap at 10%). Students are allowed to do as many design exercises as they want.

The difficulty of each Design exercise will vary. Pick based on interest. We will have fewer exercise sets than weeks of the term, and exercises will trail off near the end of term, so don't wait till Week 8 to try the Design exercises or you won't be able to get full credit on them.

2) Lateness

Due dates for online (regular) exercises, Design exercises, and checkoffs are posted on the web site. The grades for late submissions on these assignments will be multiplied by a lateness penalty P that is calculated from n, the number of minutes late:

P = max(0.0, min(1.0, 1-float(n)/(7*24*60*2)))

as shown below:

The lateness multiplier for late assignments decreases linearly from 1.0 at 0 minutes late to 0.0 at 14 days late. Assignments completed more than 2 weeks after the due date will not receive credit. For lab checkoffs, the completion of which requires your presence in the lab, only times during office hours will count toward this penalty.

This penalty is applied to each question or checkoff independently, so questions and checkoffs that were completed on time will not be penalized, even if other parts of the same lab or exercise were completed late.

The following table shows some examples:

Submitted Max Credit Received
on time 100%
1 hour late 99.7%
8 hours late 97.6%
24 hours late 92.8%
2 days late 85.7%

If you have any questions about this policy or its impact on your grade, please send an e-mail to the instructors.

3) Extensions

To help you manage your obligations, each student will be given two automatic one-week extensions. Each of these extensions applies to all regular assigments that are due in a given calendar week (typically, two labs and one set of regular exercises). The extensions are automatic: they are granted by an algorithm that is run at the end of the semester. The algorithm applies the extension to the two weeks that minimize your loss of credit due to lateness. Design exercises are not subject to these one-week extensions because they are not required in any given week. Don't worry, however, Design Exercises still benefit from our two-week rolloff like everything else (see Lateness section above).

You may use your two automatic one-week extensions for sports, music, inteviews, projects, or any other reason. You do not have to ask for the automatic extensions to be applied.

If you are experiencing personal or medical difficulties that prevent you from completing some of the work in 6.08, please talk with a dean at S^3, and, with their support, we can offer additional extensions or alternative arrangements. Without written support from Student Support Services, we cannot offer any exceptions to the rules outlined on this page.
