Take advantage of the study tools meant to supplement the Glencoe Algebra 2 book. Purchase the book new or used for just a few dollars and use the online extra examples, self-check quizzes, vocabulary review and chapter tests. When you get a problem wrong, the website not only gives you the right answer, but refers back to the page in the textbook that will explain the problem.
My daughter is practically teaching herself using this text and the online website.
