CPE Semester 2 Review 2012-2013

~140 questions, all multiple choice on Scantron
You will need a pencil and eraser
You will be given a periodic table with polyatomic ions
Any equations you may need (density, solubility) will be given to you.
Bring something to do afterward.
The test is constructed in order with each unit labeled. That is, the questions are not all mixed up.
The number of questions for each unit is proportional to the time spent on the unit. Units that went by
pretty quickly don’t have a whole lot of questions, compared to longer units.

You will be given all of the formulas on a separate sheet but you need to know what the symbols stand
for.
Use this packet to determine what to review. Go through this sheet and fill in definitions/answers.
Study this material.
Review your notes, quizzes, pre-tests, and labs from each chapter. You should be preparing for this
test just as you did for each individual chapter test.
The pre-test answer keys are available on SchoolPointe.
Look back at your test reflections. What did you have trouble with? Be sure to review those things. The
test reflection also has ideas for what you should be doing to review at the top of the page. Try some
of those things.
If you’d like to come in and look at your old tests again you can set up a time with me before or after
school.
Do a little at a time. Don’t wait until the night before the exam and try to relearn it all.
I’ve planned one day in class for us to review together. This will be a question/answer session like we
normally do before tests. You should study before this day so that you can have a prepared set of
questions to ask me.
