You are welcome to discuss your homework with other students, but each student is expected write his or her final answer independently. In the later case you'll get the same score for that question that you got on the in-class exam. If you reuse any answers from your diagnostic exam, attach your entire original exam. The marks on the exam indicate how you did. Wavey underlines indicate partial credit, either partially correct or not really correct but on the right track.
Solid underlines indicate that that part of the answer is correct.
If you omitted an answer to part of the question, that part of the question will be circled. Each question mark in the question requires a specific answer.
