TEST #2: Monday April 19



  • Participation: 5%
  • Labs: 15%
  • Assignments: 45%
  • Project: 10%
  • Test 1: 10%
  • Test 2: 15%
  • You must pass the average of the two tests (atleast 50%) to pass the class.

The plan is that there will be a corresponding assignment for each module.

Protip: Although each assignment will be weighted the same, it is inevitable that some assignments will be harder and/or require more work than others.


  • There will be weekly discussions on MSTeams or a Quiz on Learn. An announcement will be made each week when these are posted.


There are 21 lab programming exercises to be completed by students.

  • Lab handouts are normally posted on LEARN early Saturday mornings, eight days before the scheduled lab due date.
  • There are usually two labs per week. Labs are normally due on Fridays at 11:59 PM (unless otherwise indicated), see the schedule for details.
  • Labs are created by the instructor and marked by the instructional support assistants and graduate teaching assistants based on specifications drawn up by the instructor.
  • The grade will typically be available on LEARN less than 1 week after the due date.
  • All labs are weighted equally.
  • The two labs with the lowest mark will be excluded, and the remaining labs will be weighted equally.


There are 8 programming assignments.

  • All materials for the current week’s assignment are posted on LEARN before the first lab time that week.
  • Assignments are due on Wednesdays at 11:59 PM (unless otherwise indicated), see the schedule for details.
  • Assignments are created by the instructor and marked by the instructor, instructional support assistants, and graduate teaching assistants based on specifications drawn up by the instructor.
  • The grade with feedback will typically be available on LEARN within 1 week after the assignment is due.
  • The assignment with the lowest mark will be excluded, and the remaining 7 assignments will be weighted equally.

Final Project

The final project is an open-ended assignment where you design and implement a program of your choice. This is a culmination of all concepts learned throughout the term and a chance to conceive and design a complete program.


There are two tests.

  • The two tests are created by the instructor and marked by the computer (for multiple choice questions), instructor, instructional support assistants, and graduate teaching assistants based on specifications drawn up by the instructor.

Lab and Assignment Submission

All assignments and labs must be submitted to LEARN.

  • It is the student’s responsibility to verify assignments and labs are submitted to the correct LEARN dropbox, in the correct format, and that the correct files were submitted.

Lab and Assignment Deadlines

Assignments and labs that are submitted late will receive a mark of 0.

  • There are no deadline extensions for Labs.
  • There are no deadline extensions for Assignments.
  • There is no deadline extension for the Final Project.

    After an assignment or lab due date has passed, you may still submit your work for feedback only (no marks). You must inform the CS105 Instructional Support Assistants by email so they are aware of your submission and request for feedback.

Missed Work Due to Illness

If you miss an assignment due to illness or other extenuating circumstances, email Barbara Daly to confirm the documentation needed to exempt you from the appropriate course componenets. With appropriate, authorized documentation, assignment work may be excused. If a missed assignment is excused, its weight is distributed over the remaining un-excused assignments. In the interest of understanding the course material for future assignments and exams, students who miss work are encouraged to do complete it when they are able, submit it to cs105@uwaterloo.ca, and request feedback.

Group Work

There is no group work. All work must be done individually.


Academic Integrity

In order to maintain a culture of academic integrity, members of the University of Waterloo community are expected to promote honesty, trust, fairness, respect and responsibility. Please take the time and go through the following:

To better understand the basic values of academic integrity and the consequences of academic misconduct please refer to Academic Integrity tutorial.


A student who believes that a decision affecting some aspect of his/her university life has been unfair or unreasonable may have grounds for initiating a grievance. Read Policy 70, Student Petitions and Grievances, Section 4. When in doubt please be certain to contact the department's administrative assistant who will provide further assistance.


A student is expected to know what constitutes academic integrity, to avoid committing an academic offence, and to take responsibility for his/her actions (see Academic Integrity Guidelines ). A student who is unsure whether an action constitutes an offence, or who needs help in learning how to avoid offences (e.g., plagiarism, cheating) or about 'rules' for group work/collaboration should seek guidance from the course instructor, academic advisor, or the undergraduate Associate Dean. For information on categories of offences and types of penalties, students should refer to Policy 71, Student Discipline. For typical penalties check Guidelines for the Assessment of Penalties


A decision made or penalty imposed under Policy 70 (Student Petitions and Grievances) (other than a petition) or Policy 71 (Student Discipline) may be appealed if there is a ground. A student who believes he/she has a ground for an appeal should refer to Policy 72 (Student Appeals)

Final Grades

In accordance with Policy 46, Appendix A - Access to and Release of Student Information, the Centre for Extended Learning does not release final examination grades or final course grades to students. Students must go to Quest to see all final grades. Any grades posted in Waterloo LEARN are unofficial.

AccessAbility Services

AccessAbility Services, located in Needles Hall, Room 1401, collaborates with all academic departments to arrange appropriate accommodations for students with disabilities without compromising the academic integrity of the curriculum. If you require academic accommodations to lessen the impact of your disability, please register with them at the beginning of each academic term.
