Grading Policy
The weights assigned to the different components are as follows:
- Assignments 42%: Approximately 9 assignments will be assigned during the semester. The relative weight for each assignment will be proportional to the points assigned to the assignment.
- Mid-term exams 36%: Two mid-term exams will be scheduled during the semester (in class on February 28 and April 13). Each mid-term exam is weighted 18%.
- Final exam 22%
The grade cutoffs below may be lowered based on class performance. The table shows the minimum grade that will be earned for a given total score on the course. Range of [a,b) includes all values x such that a <= x < b.

Late submission penalty for assignments
For the purpose of computing late submission penalty below, 6:00 pm is considered to be the due time for each assignment on its due date. Late submission penalty for each assignment will be defined as a percentage of the maximum possible points for that assignment, as follows:
- Submission delay past due time <= 48 hours: no penalty (i.e., two day extension is granted to everyone without requiring the instructor's approval)
- 48 hours < Submission delay past due time <= 72 hours: penalty of 30% of maximum possible points.
- Submissions late by more than 72 hours past the due time will not receive credit without approval of the instructor. Approval may be granted only under exceptional circumstances.
Academic Integrity
The only materials you may reference when working on the assignments are your notes, assigned reference material such as the textbooks or course notes, the lecture slides and lecture videos (if any provided on Canvas). In particular, you may not reference other online sources. You must submit your own work, and you must not collaborate with others in preparing your answers.
You may not reference solutions from prior teachings of this course or solutions provided elsewhere.
The Georgetown University Standards of Conduct apply.
Violating academic integrity policy will lead to a zero on the relevant assignment and potential reporting to the honor council.
When in doubt, ask the instructor what is allowed.
