In this new version of Practical Intelligence Quotient PQ2 players learn to calculate their intelligence by using the new PQ scoring system.
The PIQ system was developed created by Professor Masuo Koyasu of Kyoto University in Japan. Although seeming like a series of games, PQ2 will measure your brain power and test it against your friends, your country - even your gender! Use the PSP to take your score online & measure your brain power against others
