There are often times many annoying timers on websites where you have to wait for the timer to go past before you can click to the next screen. It may be hours before you can get to take the test at the end that you already know the answers to. Websites like boat-ed.com make you wait, but there is a wait to skip the timers. For example, if you are on google chrome, you can right-click the screen to “inspect element”
At the top, the huge numbers that start with 4, are just the end of the page link so it knew where to go next such as boat-ed.com/course/content/47021
and the other one was telling it which page you were coming from.
