I did the online driver safety course. It keeps a timer on, and you can't skip to the next page until the timer is up.
When a new page popped up, I copied and pasted all the text to a word document, then minimized the window and left it. Come back later, go to the next page, and do the same.
At the end for the test, I would just do a keyword search in the word document for the answer (if I didn't know it already).
