"Practice problems mirror those found on the actual ACT in content, form, and style. Covering every topic within English, Math, Reading, Science, and Writing, the problems are organized into practice sets and come with step-by-step explanations and in-depth guidance. A diagnostic test helps you identify strengths and zero in on any weaknesses, while progress trackers and topical grading sheets help you stay motivated."-- Amazon.com viewed 6/18/2020
