All books are equally essential to help you study and pass your examinations. There is no single book that is more important to help you pass the exam. Now there are some books which do have a bit more information. This all depends on the volume and content-type. This includes more targeted questions during testing. You are still required to obtain and study all the essential books.
At Contractor Campus, we offer online courses. Within our online courses, they will also consist of General Subject Modules, Layout Studies, and R-modules. These modules will provide you lecture videos and practice questions. You will have all the study material at your own pace and have unlimited access to it. When you purchase at least one online course, they include in-person refresher classes that cover business, accounting, trade math, and how to find information within the books. These in-person classes are offered in Tampa, Orlando, Fort Myers, Miami, Jacksonville, and Fort Lauderdale.
