# Foundations of Computer Science (FOCS) Assignments

## Academic Honesty

For all graded assignments in the course (including quizzes and exams), you may use the course text, the course lectures, and your completed course assignments as reference material. For homework, you may discuss problems with other students, but all submitted assignments must be your own thinking and writing, and written independently. The level of discussion you may engage in with other students regarding homework questions is exactly the level to which you would be willing to publicly share on Piazza, where the instructor can see your collaboration — if you wouldn't share something on Piazza publicly, then do not share privately.

### Homework Instructions

- Start each problem on a new page. Do not submit code.
- Write clearly and concisely. Use proper grammar and write in complete sentences. Even if your solution is correct, if it is not well-written you will not receive full points. For examples of well-written solutions, see the solutions to the pop quizzes and exercises in DMC on the main page; examples are given for every chapter of DMC.
- Submit your solution as a pdf, electronically (see the main page). We
**WILL NOT**accept email submissions.

### Grading

For homeworks, quizzes, and exams:

- You
**MUST**show your work to get full credit, including on multiple choice questions. - Non-multiple choice questions are graded as follows:
- Correct solution (with work shown): 100%
- Significant progress (with work shown): 80%
- You understood the problem and made a reasonable attempt that failed: 50%
- Serious error or lack of understanding: 0%
