Despite the enormous capacity of the human brain, we only utilise on average two per cent of our potential brainpower. There is, therefore, the potential for each of us to considerably expand our brainpower.

Maximise Your Brainpower provides readers with a series of mental workouts covering areas of creative thinking, problem solving, memory, logical thought, mental agility and intelligence. Chapters are each designed to exercise a different kind of brain activity, with a series of newly compiled exercises, puzzles and tests.

Use this and other books in The IQ Workout Series as a fun and informative way of testing, assessing, and expanding your brainpower!
