Special Education, Skills Training, Examination, Certification, License, Certificate, Factory, Industrial, Construction, Building, Cleaning, Painting, Paint, Welding. How about using it for preparation, review, retraining, or confirming important points? I obtained it two years ago, and I don't think the content has changed since then. Due to prohibitions on unauthorized reproduction and use of the content and images of this textbook, I cannot post photos. However, I have drawn red lines on the parts that were said to be on the exam. Since I drew the red lines while fighting off sleep, some of the red lines are wavy and messy. Thank you for your consideration.
