Researchers at the University of Michigan published a truly revoluvtionary paper in 2008. They determined that training using something called the Dual N-Back Test could be used to improve fluid intelligence (the thing that helps you solve unique problems that you've never encountered before-like a rat in a maze).
Why is it revolutionary? Well firstly, fluid intelligence has long been held to be the heritable component of intelligence (it's always been figured you were only ever as good as what you were born with). What's even more remarkable is that it has never previously been demonstrated that any activity was able to improve this kind of intelligence (ie; you couldn't train yourself to be more intelligent in this domain).
These researchers tested measures of fluid intelligence then subjected 4 different groups to training using the Dual N-Back test for different lengths of time while a control group received no training. Upon retesting, the control group showed a modest improvement attributable to the retest effect; however the training groups showed massive improvement. What was even more impressive is that the longer you trained, the smarter it seemed you got (ie; there was a dose dependent relationship).
The idea is that this test improves working memory (the short term second to second memory) while forcing the student to process visual and auditory stimuli under significant time pressure......it's HARD! You can have a look at the test here:

If you're so inclined, check out the original article, it's excellent!

The only down side is that after having a crack at the Dual N-Back Test, you may find your head is ready to explode. But persevere, it will help with your GAMSAT preparation....or just make you a little sharper if that's what you fancy!
Good luck y'all
