Chinese Character Test - How many Chinese characters do you know?

Clavis Sinica has come up with a fun test to determine how many Chinese characters you know. What you do is take a quiz where you need to identify the Pinyin and definition for individual characters. Based on your score you will be told how many characters you know. While I think their estimate for me was a bit low, it was at least in the ballpark. I have 776 characters in my Supermemo database and got a score of 623 when I took the 72 character test. I think the truth lies somewhere between the two numbers. Still, though, this gives a ballpark figure. Most people don't keep track of which characters they have learned, so this gives them an idea of how far along they are.

Note: Reading instructions is never fun, but it is worth checking out the background document. It explains what the skill level means and how to set it. In short the higher levels contain tests for more words. By picking an accurate level you will get a test more finely tuned to your knowledge of Chinese characters.
