Once I order a course, how long before I can start?
You may begin immediately! Simply click the Login button in the upper right-hand corner on your desktop or in the upper-right menu on mobile. Once you’ve entered your login and password, you will be taken to your courses. Follow the instructions and enjoy!
Once I start an online course, can I start and stop it at any time?
Our courses are available online, 24/7, and you can log in and log out at any time during the course. If you are going to be away from your computer for more than 10-15 minutes, we recommend that you log out. When you log back in, you will be able to re-enter the lesson you were last in.
How long do your exam prep courses take to complete?
It depends on your learning style and comfort level with the topics we cover. There is no set time for completing exam prep courses — you go at your own pace!
Many plumbers like to re-watch materials, while others like to re-take the practice tests. Our recommendation is to go through the course as many times as you need to be comfortable with the material and any applicable reference books. The more familiar you are with the materials, the better you will do on your exam!
How long do I have access to my courses?
After you purchase a course, you have unlimited access for six months. If you need additional time, please contact our offices to arrange an extension (please note: a fee may apply).
Do your courses have tests?
It depends on course type and location. Most continuing education courses include quizzes.
Exam prep courses have a short quiz at the end of each lesson and a longer practice test at the end of the course. These quizzes and tests are there to help you practice taking an exam and identify areas you may wish to review more.
If I fail a practice test, do I have to take it again?
No. Practice tests are just that: for practice. You will have the opportunity to retake the practice tests until you do pass. The practice tests are there to help you get used to the process of using your reference materials and finding the correct answers during an exam. If you don’t pass on the first try, take the time to note what sections of the material you need to review.
Once I complete a course, can I still go back and review the lessons and quizzes?
You can review the lessons and quizzes at any time during the six months you have access to the courses.
