2015-16 CPE Semester 1 Review
Format/stuff to bring:
· About 120 questions, all multiple choice on Scantron
· You will need a pencil and a calculator, a periodic table with formulas will be provided for you.
· In accordance with school policy, there will be no electronic devices allowed after the test
· 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.
How to prepare:
· Sleep well the night before
· Eat breakfast, even if you usually don’t
· You will be given all of the formulas on a separate sheet with the periodic table. You need to know what the symbols stand for, though.
· Use this packet to determine what to review. Go through this sheet and write definitions/answers next to things you don’t know. Then study this material. If you need more room to write, a copy is on Schoolpointe that you can add spaces to, etc.
· Review the things behind each divider in your binder. If you haven’t been organizing your notebook the way I’ve asked you to, now you find out why I told you to do it that way! The things that have been three hole punched are test reflections (green), vocab and skill sheets (green), bookquizzes (pink), pretests/posttests and self-assessments (salmon), and your class notes. Basically you should be preparing for this test just as you did for each individual chapter test.
· A lot of these papers are available on SchoolPointe and have answer keys with them.
· Look back at your test reflections. What did you have trouble with? Be sure to review those things. The test reflection also has up at the top ideas for what you should be doing to review. Try some of those things, if you have not. If you’d like to see an old test, you will have to come after school to do that.
· If you’d like to come in and go through your old tests (either on your own, or with me) you can do that, but the tests don’t leave my room.
· Do a little at a time. Don’t wait until the night before the exam and try to relearn it all.
· The day before exams is time for us to review together. I am not planning any kind of formal review game or practice test, it is just an open time to fire questions at me. If you have not done any preparation on your own before then, you are wasting the opportunity to ask me questions. You may also work together and quiz each other in a small group, as long as the noise level does not get too loud and as long as you use CPE class time to prepare for the CPE test.
