Directions: Do NOT open this packet until instructed to do so. There should be absolutely NO TALKING during the exam
unless you have raised your hand and have been called on by the instructor. Failure to do so will result in one verbal
warning, and then a failed test grade.
Students should sit on opposite sides of the lab tables for this exam. DO NOT sit together on the same side.
Select the BEST answer to each question from the options given (more than one may sound right, but there is only one
entirely correct answer per question). Be sure to clearly mark your answers on the Scantron sheet. You may write on
your test packet, but only answers on the Scantron will be considered.
You may use one and only one 3x5” note card with your own handwritten note. This notecard must stay on the desk in
front of you at all times.
Exam test taking tips:
Treat each question like a short answer question if you can. Cover the answers, create an answer in your head, and then
match that answer to those given to find the best answer.
If you do not know an answer, skip it and come back later.
Use information from other questions to help you. One question may help you answer another question.
Cross off answers to eliminate and lower possibilities. If you cannot narrow the options to just one, select the answer
that sounds the best to you and makes the most sense.
Read each question AND each option carefully. Do not select an answer until you have read them all!
Good Luck!
