Assignment Guidelines:

 

General Guidelines

§   All programming assignments will be tested on CSELabsr Linux machines, using the gcc compiler when appropriate, unless otherwise stated.

§   Assignments must be submitted electronically on Canvas by midnight on the due date.

§   When working in a group of two students, both members of the group should submit the assignment. You must submit the same work, and the submission file should contain the lastnames of both students. For example: Smith-Jones-Assingment-3.pdf.

§   When using the submit utility, the name of the assignment is of the form HW#, where you substitute the actual assignment number for the # (e.g., the name of the first assignment on submit will be HW1)

§   All assignment must have the following header in the main file:

/* CSci5105 Spring 2021
* Assignment# 1
* name: <full name 1>, <full name 2 (optional)>
* student id: <id1>, <id2 (optional)>
* x500 id: <id1>, <id2 (optional)>
* CSELABS machine: <machine you tested on eg: xyz.cselabs.umn.edu>
*/ 

 

Late Assignments

Penalty on Late Assignments:

§   1 day late submission will incur 10% deduction of points earned.

§   2 days late submission will incur 20% deduction of points earned.

§   3 days late submission will incur 30% deduction of points earned.

 

Grace Period for Late Assignment Submission

§   For the duration of the course, you are given a total of five grace days which you can use to submit assignments past the due date for credit, without incurring late penalty.

§   You may use at most three grace days for an assignment unless noted otherwise. 

§   You cannot  submit an assignment three days past the due date for credit unless you are using grace days unless you are using grace days for late submission without penalty.

§   Inform the instructor and the TA when you are planning to use your grace days on a late submission.

§   It is important that you keep track of your remaining grace days so you can submit late assignments for credit. If you are unsure of how many grace days you have left, contact the instructor or the TA through email (preferable) or office hours.

§   Should you have an extenuating circumstance that requires more than three days beyond the due date or you do not have sufficient grace days left, contact the instructor and TA as soon as possible.

For Group Assignments

§   The number of grace days available to students who decide to work in groups for group assignments is the minimum number of available grace days between group members.   For example, if Alice and Bob are working together where Alice has three remaining grace days and Bob has one, then collectively, Alice and Bob can only use one grace day. 

§  The number of grace days used by a group will be deducted from the remaining grace days from each group member. Using the previous example, if Alice and Bob use their one grace day, Alice would be left with two grace days and Bob with zero. This is to prevent disputes between group members on whose grace days to use and to ensure a fair use of grace days to students who choose to work individually on group based assignments.

 

Group Assignments Guidelines

§   All group assignments must be completed by a team of no more than two students. Seeking help from others outside of your team on assignments is considered scholastic misconduct.  Please refer to the scholastic misconduct policies described on the grading policy page and also stated below.

§ Offensive or inappropriate language or images should not be used in any form of communication e.g., emails, discussion postings, group projects, and submitted assignments. This includes background images and settings in Zoom and other video platforms.

§ The discussion area of the course is reserved for postings related to course work only. Postings of a personal or non-academic nature are not permitted and may be removed by the instructor should they appear.

Scholastic dishonesty means plagiarizing; cheating on assignments or examinations; engaging in unauthorized collaboration on academic work; taking, acquiring, or using test materials without faculty permission; submitting false or incomplete records of academic achievement; acting alone or in cooperation with another to falsify records or to obtain dishonestly grades, honors, awards, or professional endorsement; altering, forging, or misusing a University academic record; or fabricating or falsifying data, research procedures, or data analysis. (Student Conduct Code: http://regents.umn.edu/sites/default/files/policies/Student_Conduct_Code.pdf) If it is determined that a student has cheated, he or she may be given an "F" or an "N" for the course.

§   Consulting and seeking help from others (students or non-students) on assignments and exams when asked to do an assignment problem individually.

§   Consulting and seeking help from others not in your group (students or non-students) on assignments when asked to do an assignment problem in a designated group.

§   Cheating on exams. Consulting others or using any material which is not permitted on the exam.

§   Copying material from some source, such as the Internet or books, and presenting it as you own solution or design when asked to solve a problem yourself.

§   Attempt to change an already graded assignment and asking for re-grading of that material.

§   Attempts to fabricate the submission date/time of a late assignment to make it appear like an on-time submission.

§   Stealing some other student's solution or program.

§   Submitting solutions prepared by the TAs and the instructors during the prior years of the course offering.

§   Obtaining information through the Internet and submitting it as your own work on an assignment.
