2. This is a closed book exam.
3. This exam contains 5 questions. You have one hour to complete it. I will suggest
not spending too much time on a single question, and work on those you know how
to solve.
4. The subquestions of a given question are listed from the easiest to the hardest.
The best strategy may be to finish only the subquestions you know exactly how to
solve.
5. There are a total of 11 pages in the exam booklet. Use the back of each page for
rough work.
6.
Neither calculators nor help sheets are allowed.
7. Read through all of the problems first, and consult with the TA during the first
15 minutes. After that, no questions should be asked unless under special circum
stances, which is at TA’s discretion.
You can also get a feel for how long each
question might take after browsing through the entire question set. Good luck!
