About Piazza

This semester, we are using Piazza for class discussion. The system is highly catered to getting you help fast and efficiently from classmates, TAs, and instructors.

Rather than emailing questions to the teaching staff, we encourage you to post your questions on Piazza. You and other students can answer a question and edit the answer, with the teaching staff chiming in as appropriate.

Use Piazza to ask anything, from questions about assignments to where to take a quiz.

Rules to follow

We have one special ground rule for us all to follow. On questions about an assignment, do not post Java (or other language) code that gives part of the answer to the assignment. That takes all the fun away from all students who are trying to solve the problem.

The job of all of us is to give hints that will help each student find the answer. Point to a place in the text or course handouts that give hints, talk about the philosophy behind or reasons for something, write things that help others find the answer themselves. But don't ruin it for everyone by giving answers as code.

Remember our Academic Integrity statement: For an assignment, you must not have or look at the code of another student in the course or provide code to another student.

CEO Pooja Sankar of Piazza

Pooja Nath Sankar is the founder and CEO of Piazza. Her story illustrates what can happen when someone with a passion works hard to translate it into reality.

Pooja went to an all-girls high school in India and was then admitted to IIT Kanpur, India. There, she was one of a handful of girls in the midst of many boys. Too shy to talk much, she studied alone, while the boys worked together, benefitting tremendously from the collaboration. Piazza is Pooja's way of providing a collaboration tool that all can use, whether they are shy or not, whether they are male or female. It fills a niche; it is far better than the wikis and threads that are in use for such discussion groups. She saw a need, figured out a way to fill the need in a really innovative way, and then used her entrepreneurship skills to make it a reality.

Pooja conceived of Piazza in in 2009 --just two years ago-- in a class during her first year at the Stanford Graduate School of Business.

Pooja has degrees from IIT Kanpur (India), the University of Maryland College Park, and Stanford. She has worked at Oracle, Kosmix, and Facebook. Read more here:

So, what will be your Piazza in a few years? You are a Cornell student. Soon, you will have the knowledge and experience and skill to make your contribution to society. The sky's the limit.
