My mum just sent me this test, it's really interesting to see it and compare to the national average!
It doesn't take very long to do so give it a go! Make sure you only check ones you can ACTUALLY define and not just words you've heard of!!!
My result was 26,600 - not as big as I'd have guessed actually, considering I did an English degree and read a hell of a lot! But I'm fairly happy with it.
Post your results below!!
Would help if I included the link
