Algebra Practice Test

(not rated)
By
Updated on Aug 24, 2011

If you have completed all 20 lessons in this book, then you are ready to take the test to measure your progress. The test has 50 multiple-choice questions covering the topics you studied in this book.While the format of the test is similar to that of the introductory test (Introductory Algebra Practice Test), the questions are different.

Take as much time as you need to complete the test.When you are finished, check your answers with the answer key at the end of the section. Once you know your score on the test, compare the results with your score on the introductory test. If you scored better on this test than you did on the introductory test, congratulations! You have profited from your hard work.At this point, you should look at the questions you missed, if any. Do you know why you missed the question, or do you need to go back and review the concept?

If your score on the test doesn't show as much improvement as you had hoped, take a second look at the questions you missed. Did you miss a question because of an error you made? If you can figure out why you missed the problem, then you understand the concept and just need to concentrate more on accuracy when taking a test. If you missed a question because you did not know how to work the problem, go back and spend more time working that type of problem. Take the time to understand basic algebra thoroughly.You need a solid foundation in basic algebra if you plan to use this information or progress to a higher level of algebra.
