Learning Outcomes

Students will demonstrate the ability to:

Class Format
Email Policy

Email (to both instructor and TAs) should be used for urgent matters and not to address project questions, lecture material questions, etc. Due to the large number of students in the instructor classes (close to a 600 :)) email should be used only when necessary. Please, keep your messages are brief as possible :).

Course Topics (Subject to Change)
Programming Assignments (e.g., exercises, projects) 40%
Semester Exams (3), (12%, 18%, 18%) 48%
Final Exam (Group Project) 12%
Grading Concerns

It is your responsibility to submit regrade requests by a specified deadline; no regrade requests will be processed afterwards (even if there are grading errors). If you don't address a grading concern by the specified deadline, we will assume you have reviewed the graded work and are satisfied with your current grade. Deadlines to address any grading concerns will be available at Grading Concerns.

AI (Artificial Intelligence) Tools Usage

The use of AI (Artificial Intelligence) tools (e.g., ChatGPT, Bing AI) for the completion of graded work (e.g., programming assignments) is not allowed and represents an academic integrity violation (see information below).

Regarding Posting of Assignments' Solutions/Implementations
Office Hours

Office hours get extremely busy the day before an assignment deadline. Help during office hours is not guaranteed. TAs/instructors cannot stay holding office hours after the office hours period ends because students are waiting for help (this applies to online/virtual office hours). The sooner you start working on a project, the better your chances of getting help. Please, leave the TA room once you have received help and do not use the TA Room as a working area.


You are responsible for creating backups of your work using any approach (make sure your work is not accessible to others). No extensions will be granted if you lose your work and you had no backups.


We will be using (Piazza) for class communication. You will not be able to register to Piazza yourself. Your instructor will register you using the email address you have in the school system. Posting of any kind of code in Piazza is not allowed.

Class Announcements

You are responsible for checking announcements (at least twice a day) we post in the announcements Piazza folder. An oldannouncements Piazza folder will have old announcements. We recommend you check messages everyday around 11:30 am and after 5:00 pm.

Excused Absence and Academic Accommodations

See the section titled "Attendance and Missed Assignments" available at Course Related Policies.


See the section titled "Accessibility" available at Course Related Policies.

For Accessibility & Disability (ADS) Students

If you are an ADS (https://counseling.umd.edu/ads) student (others ignore this information):

ADS students: you are responsible for reserving a space at ADS to take quizzes/exams (we cannot provide that support). Keep in mind ADS has deadlines regarding by when to schedule a day/time to take exams. If your main accommodation is extra time in exams and quizzes, you don't need to meet your instructor (just bring to lecture any form that needs a signature).

Academic Integrity

Please read this information carefully. We take academic integrity matters seriously.

  1. Academic dishonesty includes not only cheating, fabrication, and plagiarism, but also includes helping other students commit acts of academic dishonesty by allowing them to obtain copies of your work. All submitted work must be your own. Cases of academic dishonesty will be pursued to the fullest extent possible as stipulated by the Office of Student Conduct.

  2. Situations that often lead to academic integrity violations:
    • A student's friend/roommate shares an assignment's code. Once you provide your code to another student, you are a facilitator, even if you indicate to the student "not to copy-paste" any of it. Actually we had a case in which a student CS degree was revoked for this reason.
    • Students use online resources (github, Chegg, etc.) to find assignments' solutions. The solutions are found by several students and all will be involved in an academic case.
    • Students assume we don't have tools that check for similarities among all students' submissions.
    • Students get desperate and don't want a 0 in the assignment.
    • Students are not aware of the expectations regarding academic integrity.
    • Students assume we don't take academic integrity matters seriously.
    • You should only receive assistance from instructors/TAs. We have seen cases in which the use of tutors have led to academic integrity violations (e.g., tutors looked for assignment's solutions online).

  3. The Office of Student Conduct is responsible for handling academic integrity matters. After a report is submitted by an instructor, the case is evaluated by the office and it could result in an XF grade, degree revocation, or dismissal from the university.

  4. One of the most negative consequences of academic integrity violations is the emotional burden an academic integrity case has on a student. We have seen students extremely distraught as a result of an academic integrity violation. In many cases students chances for recommendations, TA positions, and other opportunities are negatively affected.
