- Students will learn in-class through: formal lectures, presentations and problem solving. Out-of-class learning will consist of: readings, internet research, and problem solving.
- There will be four hours of lecture per week. Some lectures might be rescheduled if necessary.
- Course material, references, links and messages will be posted on the course website (Canvas). Students are expected to read the material and to attempt as many problems as possible before attending the lectures.
- Regular assignments will be given throughout the semester.
- Office hours may be used for further explanations and relevant discussions.
- You are encouraged to discuss problems in small groups. However, you must work alone when writing up the solutions to the problems.
- Every attempt will be made for the exam questions to verify the objectives given above. Therefore, it is recommended that students regularly consult these objectives when working on problems during the semester and when studying for the exams
COURSE-LEVEL EDUCATIONAL GOALS:
This course aims to develop a thorough understanding of stochastic calculus and the standard probabilistic tools used in the financial and the insurance practice.
- Assignments 20%
- Projects and Presentations 50%
- Final Exam 30%
The pass mark is 50%. The final grade will be allocated according to the student’s achievement in the course. Under no circumstances will late assignments be accepted.
Missing an exam will result in a mark of 0 unless the student was prevented from taking it due to medical reasons with convincing evidence. Students should use the “Health Care Provider Statement” form available at http://www.sfu.ca/content/dam/sfu/students/pdf/healthcare-statement-general.pdf. Should you miss an exam, you must let the instructor know as soon as possible. Under no circumstances will make up exams be given. A student present at the start of an exam will have his/her exam marked even if he/she leaves early for any reason.
Students are expected to take responsibility for their learning. To assist students in understanding scholarly expectations, the following actions are examples of violations of the Student Academic Integrity Policy. Please note that this list is not exhaustive.
- Submitting shared work as individual work (i.e, collusion)
- Submitting an assignment or paper more than once (i.e, cheating)
- Cheating during an exam: Using any device/mobile phone to receive or share information during the exam
- Submitting a purchased assignment or essay (i.e, contract cheating)
- Falsifying documents (e.g., Doctor’s note) to gain an advantage Accessing exam information from an unauthorized source (i.e., pay to pass)

Graduate Studies Notes:
Important dates and deadlines for graduate students are found here: http://www.sfu.ca/dean-gradstudies/current/important_dates/guidelines.html. The deadline to drop a course with a 100% refund is the end of week 2. The deadline to drop with no notation on your transcript is the end of week 3.
ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS
SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.
Each student is responsible for his or her conduct as it affects the University community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html
TEACHING AT SFU IN FALL 2021
Teaching at SFU in fall 2021 will involve primarily in-person instruction, with approximately 70 to 80 per cent of classes in person/on campus, with safety plans in place. Whether your course will be in-person or through remote methods will be clearly identified in the schedule of classes. You will also know at enrollment whether remote course components will be “live” (synchronous) or at your own pace (asynchronous).
Enrolling in a course acknowledges that you are able to attend in whatever format is required. You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.
Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning (firstname.lastname@example.org or 778-782-3112) as early as possible in order to prepare for the fall 2021 term.
