Grading and Policies

Honor Code

Please respect the spirit and the letter of Stanford’s honor code. You’re welcome to talk to classmates about labs conceptually, but the implementation must be your own unless otherwise noted. For example, speaking with a classmate about why some bug might be present in your program is okay as long as your classmate doesn’t share with you a program that fixes your bug. You should not use any existing code that we don’t supply, whether it is online or otherwise. Further, copying verbatim from places like Stack Exchange is prohibited: you will learn much more if you write your own programs.

Grading Policy

80% of your grade will come directly from passing the unit tests that are distributed with the lab. The remainder of your grade will come from a manual code quality and style pass: you should not have memory errors and you should follow the style present in the lab template. When in doubt, run your program through Valgrind and follow the relevant Google Style Guide.

Late Policy

You have three late days that can be applied in day quantities. The late days are applied automatically.

Work Load

Each lab should contribute about 3 hours of work a week. If you are investing significantly more time than this, it is likely prudent to ask for help via Piazza, at office hours, or if it’s urgent, via email.


You may be wondering why CS240 has decided to add labs to its curriculum. Quite simply, we want you to practice what you learn. We believe complex systems’ concepts are best and most easily understood when they are implemented.
