Abilify regulates no compound in the brain which would be associated with improved memory or concentration.  As a matter of fact, abilify has been shown to decrease the size of the frontal lobe with extended use.  some test taking suggestions:  Vitamin C--elevated blood levels of vitamin c have been correlated with increases in IQ.  Choline, phosphotydilserine and peracetam in combination.  Piracetam is the first nootropic discovered and has zero side effects.  a very small quantitiy of caffeine (like half a cup of coffee about fifteen minutes before the test.  And if you are into the pharma stuff, what I don't recomend is ephidrine or pseudoephidrine in conjunction with a xanax.  heck, take them all, you'll still be better off than taking abilify.   Actually I only condone the vitamin c piracetam  and choline  phosphotydelserine combo.  Best of luck on your test.
