Your homework each week will be graded automatically and you will receive either a check+ (A), check (B), check- (C), or 0 (F).
When computing your final grade, a check+ is treated like a 9, a check is treated like an 7, a check- is treated like 6, and a 0 is treated like a 0. The numbers are then averaged and this function is used to map them into number grades:
(define (numeric-grade->letter-grade number)
((<= 8.3 number 9) 'A)
((<= 7.8 number 8.3) 'A-)
((<= 7.4 number 7.8) 'B+)
((<= 7.0 number 7.4) 'B)
((<= 6.4 number 7.0) 'B-)
((<= 6.0 number 6.4) 'C)
((<= 5.0 number 6.0) 'C-)
((<= 4.0 number 5.0) 'D)
((<= number 4.0) 'F)))
Homeworks are due on Fridays at 6pm. You can expect grades to be out on the following Monday. Failing that, you will have heard from the course staff regarding when to expect them.
To encourage you to revisit material you have ot yet mastered, you have the option to resubmit homework assignments after their original deadline. If your understanding of that homework has improved, hopefully so should your grade.
Each homework has two resubmission deadlines: hwN-second-round at 6pm the Friday following the original deadline, and hwN-third-round at 6pm the Friday two weeks after the original deadline. You can submit to any of the three deadlines for a homework independently. E.g., you don't need to submit to the second round to be allowed to submit to the third, etc. Resubmission grading follows the same schedule described above. Late submissions will not be accepted.
Resubmission grades are capped to an 8, halfway between a check and a check+. I.e., if you get a check+ on a resubmission, it counts as an 8.
The last time second-try assignments will be accepted will be Wednesday of finals week (June 12th), 6pm.
Collaboration is a really good thing and we encourage it. On the other hand, cheating is a very serious offense, which carries serious consequences. It's OK to meet with colleagues, form study groups, discuss assignments with them, or compare alternative approaches. But it is never ok to share code or homework solutions, or even to see each other's code or solutions. What you turn in must be your own work. Copying (or even studying) code, solutions, etc., from anywhere (e.g., other people, web, GitHub) is strictly prohibited. Be aware that we use the (highly effective) MOSS software similarity detection system. If you discuss your work with another group, please list their names in your hand-in.
It is also forbidden to share, post, or otherwise publicise your solutions. This even extends after the quarter ends. No matter how proud you are of them, no posting your solutions to GitHub; doing so is an invitation to plagiarism.
It is the responsibility of every student in this class to be familiar with and to adhere to the Academic Integrity Policies of Northwestern University and the McCormick School of Engineering. The policies can be found here.
Any suspicion of violation of these policies will be reported immediately to the Associate Dean for Undergraduate Studies. If you are in doubt whether your actions constitute a violation of the above policies, ask the instructor.
