The first link is interesting, of course everybody know the score are false but the test is fine.
Link to the test: http://memorado.fr/iqtest?r=126#.U9_djWuq_0j.facebook
The second link is free, easier if you have facebook so you just clik and fill in what part of your brain you would like obtain more capacities:
Don’t worry, these two websites are free but unfortunately I think the only choice of language is french,..I’m sorry for people who don’t speak french.
For the other, try and enjoy!
