Exam 2

This exam begins for you as soon as you click on the link below. The exam ends at 11:59 PM on Wednesday 2010 February 24. Between those two times, you may work on it as much as you like. I recommend that you get started early and work often. You may not use your late pass on the exam. The exam is open-book and open-note, which means, precisely:

• You may freely consult all of this course's material: the Miller and Ranum textbook, your class notes, your old assignments and exam, and the materials on the course web site. If you missed a class and need to copy someone else's notes, do so before either of you begins the exam. If you are not in possession of an old assignment and its grading comments (because your partner submitted it, for example) then obtain copies before either of you begins the exam.
• You may assume all concepts, algorithms, theorems, etc. discussed in class or in the assigned sections of the book. You do not have to define, develop, or prove them on this exam. On the other hand, you may not cite material that we have not studied. If you are unsure of whether you are allowed to cite material, just ask me.
• You may not consult any other papers, books, microfiche, film, video, audio recordings, Internet sites, etc. You may use a computer for these four purposes: viewing the course web site materials, writing and running Python code, typing and submitting your answers, and e-mailing with me. You may not share any materials with any other student.
• You may not discuss the exam in any way (spoken, written, pantomime, semaphore, etc.) with anyone but me until everyone has handed in the exam --- even if you finish earlier. During the exam you will inevitably see your classmates around campus. Please refrain from asking even seemingly innocuous questions such as "Have you started the exam yet?" If a statement or question conveys any information, then it is not allowed; if it conveys no information, then you have no reason to make it.

During the exam you may ask me clarifying questions. If you believe that a question is stated incorrectly or ambiguously, then you should certainly ask for clarification.

Your answers should be thorough and polished. Always show enough work or write enough comments that a classmate could follow your logic. If you cannot answer a question, then submit a brief summary of the approaches you've tried. Partial credit is often awarded. When there are multiple solutions to a problem, it is understood that simple or efficient solutions may earn more credit than complicated or inefficient ones. Exam grades are loosely curved — by this I do not mean that there are predetermined numbers of As, Bs, etc. to be awarded, but rather that there are no predetermined scores required for grades A, B, etc.

Good luck!

I have read the rules of the exam, I understand them, and I want to begin the exam now.
