It's divided into categories: grammar, vocabulary, reading, writing, listening, and speaking. There are about two questions on the right-hand page, and the answers and explanations are on the next page after you turn it. Since there are only about two questions per page, you can progress little by little during meal times or commutes, and it's convenient because you can read the explanations each time. I think it's also good to use it as a supplement for TOEIC, etc. You can read the explanations of grammar and expressions little by little. The audio could be downloaded from the website.
