Final exam on December 17th Tuesday 9am

Our final exam will be in our regular meeting room Small 111, the extra sitting will be available in Small 122. We will cover everything except materials presented during the last week (chapters 16 and 17 - Waves and Sound) also do not worry about Damped and Forced oscillators.

Note: According to Academic Regulations:

Except in narrowly defined circumstances, changes in the examination schedule are not allowed. Individual faculty members may not grant permission to reschedule or defer a final examination.

Requests to reschedule a final examination within the examination period should be filed with the Office of Undergraduate Academic Affairs. Requests must be made by the last day of classes for the semester.

The final exam day and time can be adjusted for people with SAS accommodations.
