The Level III Study Guide provides a selective, representative sample of questions like those that make up the Level III Certified Control Systems Technician (CCST) examination. The 3rd edition has been rewritten to include new questions and answers that better reflect the difficulty of the Level III exam. The questions are divided into the eight performance domains covered on the exam; each domain contains the same percentage of questions that appear on the exam. The Study Guide includes an answer key to help you determine your level of preparation, along with tables directing you to books and other resources to study for areas that you need to brush up on.
