Mathematics 33A, Practice Midterm, October 12, 2009.
Calculators, books, or notes of any kind are not allowed on the exam.
There are 11 items on this practice exam altogether, and they all have equal value. Answer
as many of them as you can in
50 minutes
. You must show your work in all questions.
The questions are not always arranged in order of diFculty. Look through them when you
start so you get an idea of the time you’ll need. If you’re not sure what to do on an item then
move onward and return to it later. (Some of the questions can be solved with geometric
reasoning instead of lengthy computations; this may save you some time.)
After taking the practice test, grade yourself as follows: ±or each fully correct answer give
yourself 5 points. ±or a score at the A range you should aim to have fully correct answers
for at least 9 questions, within the allotted 50 minutes.
Good luck.
