  • Assignments are posted on the Homework tab here. They are due by 9:59 pm on the day due (noted below) on Gradescope.

Course staff will define what constitutes a "good attempt." We will be looking for reasoning and detailed work shown – it is assumed that you will show work or provide reasoning whether or not the question asks for it.

Academic Honesty

Being an online class academic honesty is of particular concern. I will do everything I can to remove incentives for you to feel like you need to cheat. Please know that I take the Berkeley honor code very seriously and have years of experience catching cheaters. If we suspect someone of cheating, we reserve the right to give the student an oral quiz or exam and test if the student understands what they wrote.

Please familiarize yourself with UCBs Academic Honesty Policy (see the Center for Student Conduct website: ). I encourage you to discuss homework problems with other students and to work together, but copying is never appropriate. (You should never write down anything you don't understand!) I strongly encourage you to familiarize yourself with the definition of plagiarism, and to avoid engaging in it. Violations of the UCB’s Academic Honesty Policy, including instances of plagiarism, will be reported to the University and an appropriate penalty will be implemented. (This may range from a failing grade on an assignment to an “F” for the course, in addition to writing letters of reflection and apology to UCB’s administration.)
