Problem Set InstructionsProblem sets are posted on the Stellar website. Precise due dates are posted in the class schedule.How to Submit Your PSETYou should prepare a pdf file for your pset submission, with individual problems on separate pages of the pdf document. Scans of hand written solutions are fine.You will submit your pset solutions online on the Gradescope website. Log into
Gradescope with your MIT
email address and entry code 9YVPDJ. Click on the
6.042 Course Page, where you will see all the currently available
psets. Click on Pset Activity & Effort StatementThere should be an Activity & Effort Statement at the beginning of each problem saying: "I spent approximately <#> hours and <#> minutes working on this problem, and I worked on this problem
OR
The grades for a problem will not be approved until its activity statement is submitted. Collaborators must write solutions in their own words by themselves. Helping a classmate with a solution, or letting a classmate look at your solutions counts as an activity that requires citation, even if you received no reciprocal help. If you helped someone after submitting your own activity statement, notify your coach and email 6042gradesmaster. CopyingYou don't get into MIT by cheating methodically, and few students, if any, would think cheating was OK. But under the pressure of multiple deadlines and perceived overload, students will sometimes copy solutions. Pset solutions are often easy to find on the web  or from a collaborator  which increases the temptation to copy and/or to "forget" to cite a source or collaborator that provided the solution. Resist the temptation to copy!
You won't get any credit simply for copying, but as long as you give an accurate citation of the source of a solution you found, you will not be subject to any disciplinary penalty. The firsttime penalty for an inaccurate collaboration statement on a submitted problem solution will be denial of credit for the entire pset. Late SubmissionsLate submissions will not be accepted once the solutions are posted. Note that solutions are generally posted promptly after the time problems are due. Concerns about Specific GradesFor specific concerns about how a pset or exam problem was graded, students should go first to their Team Coach. If the Coach is confident about a regrade, they can change the grade. If a student's concerns are not resolved by their Coach, they may appeal to a class session supervisor right after class, or send email to 6042gradesmaster@mit.edu. Notes on Proofs in GeneralProofs must be clear enough for graders to understand without undue effort. A poorly written proof, even if ultimately `correct,' will lose points. You may assume basic results from high school math and calculus, but you should explicitly mention any nontrivial assumptions. Generally, a set of equations alone is not enough for a clear solution  at least brief explanations in words are usually needed. When a problem asks for the use of a certain method (say, Well Ordering), proofs that use other methods will lose points. When there is a template for proof organization (as there are for proof by cases, contradiction, well ordering and induction, for instance), try to follow it, at least for the first few weeks of class.
