General InformationLast Updated  •  October 25, 2018
PLEASE NOTE:
Cellular phones, iPods, Blackberries, Bluetooth, headphones, computers, pocket calculators, dictionaries, translators or, in general, ANY KIND of electronic device CANNOT be used during the test.
All electronic devices MUST BE TURNED OFF: if a cell phone rings, if a light is visible, or a device is on while in class during test time, you will not be allowed to finish your test and your result will be invalidated.

You cannot use any text, manual, note, dictionary, pocket calculator, flash card, or any other source of information except your brain. You will NOT need a ruler for this test.

You will ONLY need to bring:

  1. one Scantron, Form 882-E
  2. a number 2 pencil
  3. an eraser

This study guide must be interpreted (literally) as a guide to the study of the subject and not as a listing of possible questions.
There is no additional information compared to what has been said, discussed, shown, illustrated in class.
It is YOUR personal responsibility to cover the materials listed below on the lecture textbook, on the lab textbook, on the web pages, and on your notes.

I would strongly recommend that you peruse your notes for completeness of information: some information that has been detailed in class is only mentioned briefly on the textbooks, and you are responsible for covering that; know what the key terms and concepts are (see the list at the end of each chapter on both your textbook and your lab manual); exercise with the questions for review also found at the end of each chapter. Review the materials from your quizzes.
Read the summary at the end of each chapter, try to answer review questions, try to work with other fellow students if you find it useful.
Never hesitate to ask me questions in class or during the lab.
