Courses help you prepare for the COLORADO state plumbing examination. Courses consist of several up-to-date practice exams covering the question material on the actual exam, with one-on-one tutoring available throughout your course, for a recommended 20 - 30 hours of classroom time. You will be given two months to complete the course. During this time you may come and go as you wish, but allow enough time to complete the course before taking your examination. All COMPLETED courses are "GUARANTEED PASS". 97% of our Plumbers pass the first time.
