Important: self-care
Please take care of yourselves and your loved ones. Your physical and mental well-being is the most important thing. It has always been (or should have been) so, even before the pandemic. Please email/message me to check in if I won’t see you or hear from you on a day we have class or an assignment is due.

Course expectations for out-of-class work
To succeed in this 3-credit class, it is expected that you commit a total of 12 hours per week to master the course material. This includes 2.5 hours of lecture time and an additional 9.5 hours dedicated to independent study and coursework. This time commitment aligns with the expectations set by the Computer Science department for major courses and adheres to university policies. Recognizing that dedicating this amount of time outside the classroom is a significant commitment, it is nevertheless necessary for success. Please plan your course load accordingly.
Midterm and final exams
Each exam will focus on the most recent material. However, each exam will very likely include some questions aimed at the material covered by the earlier exam(s). Make-up tests may only be given if there is a written proof of a serious reason for missing a test (such as illness or accident).
Important: you must earn at least 60% on the final exam to pass this course.
Labs and course project
During the labs and the course project students will work on hands-on problems focusing on the material covered in class and the corresponding reading materials. Students are required to work on labs individually. Each lab must be demonstrated in class no later than one week after the lab date; all relevant code must be submitted using BlackBoard. Late submissions for labs will be accepted during the 'make up' labs for no more than 50% of credit.
Course project must be completed by students working in teams of two. Each team will demonstrate their work to the rest of the class at the end of the semester.
Academic misconduct
All students are expected to demonstrate integrity in the completion of their coursework. Academic integrity means doing one's own work and giving proper credit to the work and ideas of others. It is the responsibility of each student to become familiar with what constitutes academic dishonesty and plagiarism and to avoid all forms of cheating and plagiarism. Students who engage in plagiarism and other forms of academic misconduct will face academic and possibly disciplinary consequences. Academic sanctions can range from a reduced grade for the assignment to a failing grade for the course. From a disciplinary standpoint, an Academic Misconduct Report may be filed and a Faculty Hearing Board may impose sanctions such as probation, suspension or expulsion.
For further information on academic misconduct and its consequences, please consult the Student Code of Conduct and the Academic Misconduct Policy.
Attendance
All students are expected to attend class sessions regularly. However, recognizing individual differences, each student is responsible for his/her own attendance and for making-up any missed study or work. Limited assistance will be offered to those with plausible reasons for absences; unexcused absences will result in the student being completely responsible for the make-up process.
Students with disabilities
Please contact me privately to discuss your specific needs if you believe you need course accommodations based on the impact of a disability, medical condition, or if you have emergency medical information to share. I will need a copy of the accommodation letter from Student Disability Services in order to arrange your class accommodations. Contact Student Disability Services if you are not already registered with them. Student Disability Services maintains the confidential documentation of your disability and assists you in coordinating reasonable accommodations with the faculty.

Here's a link to a document containing information about other policies and resources.
Grades and evaluation
Students will be evaluated regularly during the semester and should be aware of their progress continuously during the semester. The final course grade will be reported according to the stated University policy.
To pass this course with a grade of C- or higher, you must pass the final exam with a 60% or higher AND earn an overall course average of 70% or higher. Note that if your final exam score is below 60%, then the highest final grade you can earn is a D+, regardless of the overall course average.
The final course grade will be calculated according to the following distribution of points:
Labs (10 labs @ 2 pts each) | 20 |
Course project | 15 |
Test 1 | 20 |
Test 2 | 20 |
Final exam | 25 |
Total | 100 |
Course letter grade will be determined as follows:
A | A- | B+ | B | B- | C+ | C | C- | D+ | D | D- | F |
---|---|---|---|---|---|---|---|---|---|---|---|
94-100 | 90-93.99 | 87-89.99 | 84-86.99 | 80-83.99 | 77-79.99 | 74-76.99 | 70-73.99 | 67-69.99 | 64-66.99 | 60-63.99 | 0-59.99 |
