My first time through, I had 179,864 in level 6 . . . my IQ was 92
Africa and Central Asia are killing me . . . and I still know much less than I should about South/Central America - keep making stupid mistakes there.
Edit: New high . . . 414,708 on level 10 / IQ of 116
Edit II: I'm a little obsessed now . . . gets a little easier as you keep going since there is quite a bit of repetition in the places, so you can learn . . . which isn't a bad thing! . . . anyway, now up to 451,596 on level 11 / IQ of 120
