Algebra 2 Honors Final Exam Review GuideTo prepare for your final exam, please follow these suggested steps. The more practice you do, the better prepared you will be for the exam. Be sure to have your calculator ready the day of the exam with WORKING batteries and more than one sharpened pencil. Do not expect to borrow materials.

1. Review key vocabulary terms at the beginning of each chapter or use the list at the end of the chapter in the review.

2. Read the chapter summary at the end of each chapter several times. Write down any ideas that are unclear.

3. Review the quizzes and tests you have already taken and be sure that you would get 100% if you took the same test today.

4. Complete the chapter review and chapter test practice at the end of each chapter.

5. Use pages 1015-1016, 1020-1023 (chapters 6-7, 11-14.3) for extra practice problems for each chapter.

6. For additional practice on areas you may use previous homework assignments. Your homework should be a solution key to check your work.

7. Answer the remaining questions in this packet. Do not rely simply on these questions. These questions are only a basic outline of what you should be familiar with for the exam.

*REMINDER: Bring all quizzes and tests to the exam for extra credit on the final!! You must have all of them or no credit. There are 11 and they are listed below:
