Instructor Information:

Hello again! I’m Samina Ehsan, and I am the designer and instructor of CS-225_40X(0/1/2/3/4/5): Discrete Structures in CS. This course deals with the mathematical and theoretical concepts that you will need in the later courses in this program. I hope you enjoy the course.  

My office hours are on Tuesdays 4:00 - 6:00 pm PDT (fixed)  via MS Teams/Zoom. However, you can always email me at to schedule an office hour by appointment if you are unable to attend my fixed weekly office hours.


 Communication Policies:

  • Ed Discussion is the best way to reach me for any course-related queries. We (the instructional team) can refer back to our previous discussions here and also as it will be visible to the entire class so the other students will be able to get benefit from it.  Not all posts require a reply from us and often it is better for students to hash out an answer to a question. But please email me ( if you do not receive a reply within 24 hours.
  • I can be reached via the class-specific MS Teams/Zoom during my office hours. I also check MS Teams frequently outside my designated office hours so you can tag or DM me (@ehsans)  if required.
  • Sending an email at ( is a preferred way only for a matter of a personal nature related to the course, or scheduling a meeting outside the fixed office hour timings, or if you have not received a reply to your post/message on Ed Discussion/MS Teams within  24 hours (please include the prefix CS225_40X_U22 in the subject). Please resend me the email if one of us does not respond within 24 hours. 
  • I and the ULAs try our best to monitor Canvas email. But there are fewer options to sort and filter mail via that system so there is a much higher likelihood that we will miss things that get sent via Canvas mail. So, We strongly recommend that you do not use it.
