Lectures:
Monday 8:40-10:20 M13
Wednesday 11:40-12:20 M13

Grading:
Exam 1 (30 points)
Exam 2 (30 points)
Final Exam (40 points)
Notes:
**The lectures will be conducted face to face. I plan to upload lecture notes and videos to ODTUClass.
**The exams will be in class. Any student who did not miss both of Exam 1 and Exam 2 can take the final exam. If the exams are to be conducted online as a result of unseen circumstances, you will need a camera (smartphone’s camera or webcam) and a reliable internet connection for the the midterm and the final exam. In this case, the midterm exams will be written over Zoom with camera and the final exam will be a written/oral exam over Zoom with camera.
**Make-up Exam: For students who have been unable to take any one of the exams for legitimate reasons (such as medical emergencies), a make-up exam will be offered. The make-up exam is usually harder than the final exam and takes place after it. The grade obtained at the make-up exam is then treated as the grade obtained in the exam that was missed.
**Information for Students with Disabilities: To obtain disability related academic adjustments and/or auxiliary aids, students with disabilities must contact the course instructor and the METU Disability Support Office as soon as possible. To contact the Disability Support Office, you may visit the office located at METU Library-Solmaz Izdemir Hall, call (+90) 312 210 71 96, or e-mail to engelsiz^^metu.edu.tr
**Academic Honesty: The METU Honour Code is as follows: "Every member of METU community adopts the following honour code as one of the core principles of academic life and strives to develop an academic environment where continuous adherence to this code is promoted. The members of the METU community are reliable, responsible and honourable people who embrace only the success and recognition they deserve, and act with integrity in their use, evaluation and presentation of facts, data and documents."
**Attendance will not be taken in this course.
