I took the Extra class test once for fun .... It wasn't very funny
Needless to say , I believe I'll stay at General class .
Its pretty tough - I've seen something like 24% of the material, and my aptitude level is currently at 14% (you start a 0,0). A lot of stuff I don't know and never knew, a lot of stuff I knew at one time, some stuff that I still know - some of it fairly obscure, and the rest is common sense. I'm done studying for the nite...
