Work the official released sample clusters, each mapped to the chapters that teach what it asks. Read the chapter, then try the real questions.
How the exam works. Each cluster opens with a real-world phenomenon, then asks 5 or 6 questions that build on shared data and diagrams. Roughly 60% are multiple choice and 40% are constructed response. A scale score of 65 passes. The reference tables are open-book. These released clusters are the closest thing to the real exam that exists right now.
