They use massively privacy-invading measures to ensure that you don't do that. I don't know about Pearson specifically, but there are horror stories from the "proctoring" industry about what people have to put up with.

For example: "facial detection, eye tracking, and algorithms that measure “anomalies” in metrics like head movement, mouse clicks, and scrolling rates to flag students exhibiting behavior that differs from the class norm" As is widely known, facial detection doesn't work as well for dark-skinned people, and eye and head movement of so-called "normal people" is not fair to people who are not cheating, but not "normal".

And you can't leave your desk because you might have something out of camera sight to help you cheat. Straightforward right? Not really: "A University of Florida student felt forced to vomit at her desk when the proctor threatened to fail her if she left the screen (Harwell, 2020). She vomited at her desk in front of the stranger."

Maybe you can get away with hiding notes on another device or paper, but they try hard to make that impossible. They want to you to get up and show them everything in the room before you start your test. They want to see your hands at all times, and even track your eye movements. If your eyes are always darting to a certain area off screen where you might have notes, they might interrupt your test and demand to be shown what you're looking at. If you look up or off to the side when you're thinking, they're going to demand that you show them what you're looking at too. If you think you can scroll through notes on your phone... maybe. But, they often demand that your hands be visible on-camera at all times.

It's an arms race, and sometimes people do manage to cheat, but when that happens the proctoring companies just implement more and more outrageous surveillance.
