Pages AL12–AL16 of this text include a section called Countdown to the Alabama Test. Each page contains 8 multiple-choice problemsthat are just like those you might see on standardized tests, such as theSAT 10. You should plan to complete one page each week to help youprepare for the test.

Plan to spend a few minutes each day working on the problem(s) for that day unless your teacher asks you to do otherwise. If you have difficulty with any problem, you can refer to the lesson that isreferenced in parentheses after the problem.

Your teacher can provide you with an answer sheet to record your work and your answers for each week. A printable worksheet is alsoavailable at al.msmath2.net. At the end of the week, your teacher maywant you to turn in the answer sheet.

Your textbook contains many opportunities for you to getready for the Alabama Test every day. Take advantage of these so you don’t need to cram before the test.

• Each lesson contains at least two standardized test practiceproblems. You can use these problems every day to keep your test-taking skills sharp. The Mid-Chapter Practice Testand the Chapter Practice Test also include standardizedpractice problems.

• Worked-out examples in each chapter show you step-by-step solutions of multiple-choice test problems. Test-TakingTips are also included.

• Two pages of Standardized Test Practice are included at theend of each chapter. The first page of this practice includesmultiple-choice questions like those found on the AlabamaTest. These problems may cover any of the content up to andincluding the chapter they follow.

Go to bed early the night beforethe test. You will think moreclearly after a good night’s rest.

Read each problem carefully,underline key words, and thinkabout ways to solve the problembefore you try to answer the question.

Relax. Most people get nervous when taking a test. It’s natural. Just do your best.

Answer questions you are sure about first. If you do not know theanswer to a question, skip it and go back to that question later.

Become familiar with commonformulas and when they should be used.

Think positively. Some problems may seem hard to you, but you may be able to figure out what to do if you read each question carefully.

If no figure is provided, draw one. If one is furnished, mark it up to help you solve theproblem.

When you have finished eachproblem, reread it to make sureyour answer is reasonable.

Make sure that the number of thequestion on the answer sheet matches the number of the question on which you are working in your test booklet.
