I just stumbled across this reading test that assesses how fast you read at your normal pace. (My score was 369 WPM - 48% faster than the national average.) The free test includes a just a few comprehension questions and in all will only take a few minutes.
The most interesting part comes after you get your results. You are then presented with a list of books (Harry Potter, War and Peace, etc.) and info on how long it would take you to complete these books. It also tells you how many books you can read on a variety of devices before losing battery life. This is a great resource for reluctant readers to get the idea that some books really are not out of their league.
What do you think?
