MAKE UP EXAMThis test is governed by UFs academic honesty code. It is intended to have 35

multiple choice questions. Please check to be sure your copy has all 35. Chose the

best answer for each question.

The next is important: Unless you are specifically told otherwise, on this test do

notassume that demand or supply is either perfectly elastic or perfectly inelastic.

On the bubble sheet, please enter:

1. Your name and initials

2. Your UF ID number

3. Form code: A

4. Sign your name on the bubble sheet.

TURN OFF ALL CELL PHONES AND OTHER

COMMUNICATION DEVICES

Check that the form code and UF ID number you bubbled-in are correct now. Also check

to be sure your name is correctdo it now. I investigated the rumor that the ability to

correctly record these had been mastered by a few students at FSU. This rumor turned

out to be false. But, the rumor that an accounting major and a journalism major did

successfully record these on a test is true. These students have since been bronzed and

are on display outside their respective colleges to serve as an inspiration for all other

accounting and journalism students.

CHECK YOUR FORM CODE AND UF ID NUMBER. IF YOU GET EITHER OF THESE

WRONG, YOUR TEST MIGHT NOT BE GRADED AND IF IT IS GRADED, YOU WILL

LOSE 6 POINTS (which equals 2 questions)!

I have become increasingly concerned that some students are at a real disadvantage

because they are unwilling to ask questions during the exam while others ask a lot of

questions. Hence, to level the playing field, I have decided to eliminate allquestions

during the test. I dont like this policy, but it seems the fairest policy.

Do not ask questions of me or the TAs; in the interest of fairness I

have instructed them not to answer any questions during the exam.You will have one hour (60 minutes) to complete the exam andbubble in all your

answers. When the TAs say that time is up, you musthand in your exam. We will not

give extra time to finish bubbling in the answers, so be sure you are done when the 60

minutes are up. Of course, you may hand in your test at any time before the 60 minutes

are up.
