Book updated Jul 2026. In Michigan it is the LARA that administers licensing. Since June 2008 an applicant must complete 60 hours of approved pre-licensing education prior to taking the exam. The exam has two portions and this book covers the Business and Law portion. There is no way you can pass the exam without having solid real world experience. Our notes give you knowledge, principles and concepts. To master the topics, you must be “in the field” – you need to go through the real world plans, the various contract documents and the various administrative paperworks all by yourself. And you need to know how the experts get things done. To succeed in the exam, you also need to read as many reference books as possible. There is no single book that can cover everything!
