Exam format: Typically, there are 10 multiple-choice questions plus one 1 extra credit question (multiple-answer) on the test.  One or two Matlab-related questions will be tested. At the end of the actual exam, you will see the following questions. You should answer the last two questions only when you are ready to submit your exam. Be sure to watch the timer!  Canvas submits your test automatically when the time is up, and you need to make sure that you have enough time to answer the last two questions and perform the required procedure. If you run out of time for the last two questions, be sure to report them (the link can be found on the exam review page) immediately after the exam. 

Type YES into the blank below after reading the following: I understand I have to upload my work in the last question of the test.  Work submitted through email will have a deduction of points.  ONLY if there are extenuating circumstances and I have technical difficulties when uploading work, I am to screenshot the technical issue when submitting my work to my teacher through email. You can email Mr. Brown at wbrown@dwight.global or Mrs. Thul at lthul@dwight.global. Not leaving enough time at the end of the test is not a technical difficulty, you are to plan for the last 10 minutes to upload your work. There is only one attempt on the Week 17 Similar Triangles Test. I understand I am to enter my answer for each individual question inside the blank provided.
