Asking Questions About Homework
We will use Piazza for homework and class discussions. The system is highly catered to getting you help fast and efficiently from classmates, the TA, and faculty. Do not email questions to the teaching staff; instead post your questions on Piazza. If you have any problems or feedback for the developers, email team@piazza.com.

Click on the Piazza link on the sidebar to access our Piazza page.

Do not ask if your solutions are correct: the point of the homework is to have you try and solve a problem on your own. Do ask clarification questions and do ask conceptual questions.

Instructions for how to form blackboard groups can be found here.

Unless otherwise indicated, homework is due by 10:00PM on the due date (Tuesday nights). Sometimes, homeworks will provide a link to a questionnaire for you to fill out so we can improve the course.

We will not even look at anything you submit that is checked in after the homework deadline. Late homeworks will not be accepted under any circumstances.

Challenge Problems are designed to let you explore a topic in more depth and are more challenging than homeworks and labs. Challenge problems are optional. Some of them provide extra credit. If you want extra credit, you must work on them individually, with no help from anyone or any external sources. No partial credit is given for challenge problems. Finally, for extra credit, you must submit a solution by the deadline.
