Algebra 2 Semester 2 Final Exam Study Outline 2013 Semester 2 Final Exam Study Tips and Information The final exam is CUMULATIVE and will include all concepts taught from Chapter 1 through Chapter 13. However, the exam will PRIMARILY focus on the concepts covered from Chapters 6.3 through Chapter 13, as well as vectors. This guide will outline concepts IN THE CHRONOLOGICAL ORDER that we covered them this year! Your binder is an excellent study tool. Review all notes to decide what material has been emphasized. Look at and REDO homework problems with which you struggled! Use the homework solutions on my website to check your answers! Do EVEN numbered problems in the book from sections that we covered. Use the homework solutions on my website and come to extra help to check your answers! Study your old quizzes and tests and practice CORRECTING mistakes that you made on them! REDO quiz and tests problems with which you had trouble! Know the meaning of all math vocabulary. Be able to explain them to someone else who knows nothing about math! Additional practice is available within the online book website- if you click on the Additional Practice tab for each chapter, under the Student Resources heading you can complete the Interactive Practice Test for each chapter. Under the Lesson Resources heading, you can do interactive practice quizzes and extra practice worksheets for each lesson. REMEMBER- the more you practice each type of problem, the more you will feel confident and succeed on the exam! LASTLY BUT MOST IMPORTANT- do NOT wait until the night before the semester final exam to study! A least a COUPLE OF WEEKS before the exam, you should divide up your studying so that you focus on 2 or 3 sections of a chapter each night. Eventually, figure out what concepts you struggle with the most, and focus on practicing those problems the last night or two before the exam. 1
