PRACTICE EXAM # 1 (September 25, ’07)– MA 225 B1 – Emma Previato
THE ACTUAL TEST WILL BE SHORTER. THE SAMPLES HERE ARE INTENDED TO GIVE YOU
ENOUGH PRACTICE ON EACH TYPE OF QUESTION THAT WILL APPEAR ON THE ACTUAL
TEST.
Calculators are permitted but should not be necessary. No books or notes are permitted. You will have 80
minutes (12:30–2:00).
VERY IMPORTANT:
We were granted a larger room. The exam is in
COM 101
(
NOT
the same room
where lectures are held).
Please show your work: to get credit, you need to show that you learned the method required by the
question. The right answer without work will not earn credit.
Please write clearly. It pays to set up your work and write what you know (relevant to the question),
even if you do not reach a final answer, partial credit will be given for correct parts.
Solutions to the inclass exam will be posted on reserve in the library. Exams will be returned graded
at the end
of class Tuesday, October 2.
