The Longman CD-ROM has two sections, a skills section and a practice test section. The skills section has all the parts of the test, but without timing, and with helpful hints you can view when needed. This is ideal for becoming familiar with the nature of the test--what it looks like, what the questions are like, and how to navigate through the test. After you are finished answering the questions, you can check your answers, and there are explanations to help you understand why the correct answer is correct. For the writing portion of the skills section, it takes more of an instructional nature than writing practice. You are given sample essays and asked questions to identify the different parts of the essays as ways to help you understand what is required for the essays on the test
