With 2022 well underway, there is still plenty of time to earn your CPO® certification. If you haven’t already signed up for a 2-day course, you can register now! However, in order to pass the exam this year, you’ll need to answer with the correct CPO® test answers for 2022. There is no way to receive a sneak peek of the current questions and answers that you may encounter come test time, but there are plenty of resources at your fingertips to ensure that you know everything you need to know when sitting down for your exam. Let’s review!

## CPO® Book

Remember, the CPO® exam is open-book and open-note. That means you will have all the CPO® test answers for 2022 you need inside of your CPO® book. With that said, you don’t need to commit the book to memory, but we recommend reviewing the text, how it’s laid out, the chapter guides, charts, and reference sections. This will give you a better idea of where to look when searching through your book for the answers.

However, wouldn’t it be easier to take the test if you knew the answers without having to search for every single one in the book? That’s where the rest of our helpful resources come into play.

## Sample Problems

If you’ve taken a test before, you know that sometimes questions can be a bit tricky. Make sure to take your time reading each question to avoid any confusion. To further prepare yourself for the 50 questions that await you in your CPO® exam, we have a collection of sample problems.

From multiple choice and chemical adjustments to surface area and volume questions, we offer a variety of sample problems to prepare you for your CPO® exam. We also have many printable charts that you can use during your exam. If you want to have a better chance of having the correct CPO® test answers for 2022, we highly suggest you check out our sample problems.

## Pool Calculator

Finally, we have a handy pool calculator that you can use to practice calculating pool math problems and come up with the correct CPO® test answers for 2022.  First, our basic pool calculator allows you to determine the approximate volume of any pool, regardless if it’s a rectangle, circle, oval, or pool with a shallow and deep end. We also make it easy for you to complete distance conversions (i.e. yards to feet), amount conversions (i.e. ounces to pounds), and average depth.

Our more advanced pool calculator will allow you to calculate the ideal levels of chemicals in your pool depending on the volume. This calculator will certainly be helpful after receiving your CPO® certification and maintaining your own pool. While you can’t use the pool calculator for the exam, you can use it in real life when you get back to your pool.
