No required textbook.
Students will demonstrate the ability to:
- Understand and develop web pages using HTML and CSS features.
- Understand the mechanism to provide data persistence in the back end.
- Lectures will be recorded (if this represents a problem for you contact your instructor).
Keep in mind that technical problems may prevent us from creating a recording. You
are still responsible for any material covered in lecture and lab/discussion session.
- No pop quizzes.
- Lecture and lab/discussion session attendance is NOT required, however,
you are responsible for
any material covered in lecture and lab/discussion session.
- You do not need to notify your instructor if you will be missing lecture or lab/discussion session, unless
graded material (e.g., exam) takes place on that particular lecture.
- We may have a limited number of online office hours in addition to on-campus office hours.
- The course will have approximately seven programming assignments (projects/exercises). There will be
no semester-long projects.
- All programming assignments will be individually developed, unless specified otherwise.
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 1000 :)) email should be used only when necessary.

|Final Exam (Group Project)
It is your responsibility to submit regrade requests by a specified deadline;
no regrade requests will be processed afterwards (even if the 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
- Deadlines -
All assignments are due at 11:55 pm and you have until
11:55 pm of the next day to submit your work with
a 12% penalty. You will not receive any credit for a submission
after the late deadline. The submit server will use 11:56 pm as the deadline,
otherwise assignments submitted exactly at 11:55 pm will be considered late.
The actual deadline for assignments is 11:55 pm. A submission one minute
late is considered a late submission.
- Submit Server -
You need to use the
submit server to submit
you work. We will not accept work submitted otherwise (e.g.,
- Which Assignments Gets Graded -
Your last submission. If you have both an ontime and late submission
only the late one will be graded after a 12 pts penalty is applied (we
cannot select the highest scoring one between on time and late).
- Closed Assignments -
All programming assignments in this course are to be written individually (unless explicitly
indicated otherwise).You may discuss assignments only with TAs, instructor or via Piazza.
- No Pop Quizzes/Pop Lab Work -
There are no pop quizzes (only exams).
- Projects and exercises are posted by 6 pm on the day specified on the schedule.
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
Posting of any assignment solution (even after the course is over)
in a publicly available online location (e.g., github, Chegg) is prohibited under
the Code of Academic Integrity (facilitation of academic dishonesty). Any
student responsible for publicly posting assignments' solutions will be reported
to the Office of Student Conduct and risks the sanction of an "XF" in the course.
Posting of your assignments in a private repository where only selected
people (e.g., potential employers) have access is OK.
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). You are required to submit your
work to the submit server often, so you have a backup copy. No extensions will be
granted if you lose your work and you had no submit server 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.
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.
Excused Absence and Academic Accommodations
See the section titled "Attendance and Missed Assignments"
available at Course Related Policies.
Even if you have a valid reason for missing a quiz or an exam, you
still have to let Pedram or Nelson (not a TA) know BEFORE the time
of the exam/quiz. We have no obligation to provide a makeup even
with a valid excuse if you send us an email AFTER the exam/quiz.
Simply put, if there is an issue, say something as soon as the
issue comes up.
As for a note from a physician, please provide one from the UHC
or a local office, where you can get an actual signature. Notes
provided by an online service that never see you in person will
not be acceptable.
See the section titled "Accessibility" available at
For Accessibility & Disability (ADS) Students
If you are an ADS (https://counseling.umd.edu/ads) student (others
ADS students: you are responsible for reserving a space at ADS to take
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 any form that needs a signature to lecture).
Please read this information carefully. We take academic integrity
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.
- 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
- 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).
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.
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.
