Certified Pool Operator Practice Test, Quiz, and Flash Cards

This self-guided course provides a proven track of CPO Class preparation and is second only to our CPO Live Virtual Prep class (highly recommended). The class itself is relatively quick-paced. The instructor has a lot of information to review in the two-day course. The videos we have created are a nice contrast from the speed in which the class information is provided. The cool thing about the videos is that you can pause, rewind, or view multiple times. This allows you to ensure that you thoroughly grasp the concept. ​​ Take the CPO Practice test today!

Student Testimonial

How to take the class, How to take the test

This next video is really important. As I had mentioned above, there are fifty questions on the CPO Certification test. It is important to know going into this that only ten of these questions involve any type of math. Insert Sigh of relief.

This, of course, means that there are forty questions that are not math. This next video focuses on suggested school supplies, how to take the class, navigating the handbook, and taking the test. What to look for in the handbook and note taking that will simplify the exam.

The Pool Math

Math is an extremely small portion of the test. That said, it does take up an extremely large part of the program. In fact, as you go through the actual class it’s going to feel like the whole darned thing was math. But, don’t stress it – just ten math questions.

This doesn’t mean I am trying to minimize the importance of math. Far from it. The math is extremely important for everything we do. Still, no one is expected to memorize it all in a 16-hour program. The goal is that the more you refer back to the materials the more it commits to memory. This next video is actually a playlist of a quantity of six. Don’t get alarmed – each video is less than 10 minutes long, so you can watch all six in an hour or a couple at a time.

Chemicals, Maintenance, Troubleshooting

Again, a large portion of the CPO class involves familiarity with honestly everything from A to Z. You will not leave this class an expert, not by any means. But, you will have a great foundation on which to build. Don’t get me wrong, you will learn a lot. The following is a playlist of seven videos that will touch base on a little bit of a lot of things that you may find helpful.
