Academic Honesty Pledge

I completed the test by myself, without help from other students or visitors besides my teacher/s. I did not look up any of the questions, and I didn't violate any of my school's testing norms.

There are private reasons where I cannot sign this pledge, and I need to talk to my teacher in private.
