almost there, but not quite there category candidates, a 5 mg shot of methylphenidate half an hour before the CAT begins would very likely give them an extra focus during the duration of the test - an extra focus that can prove very decisive and earn them a few extra points.

Methylphenidate is a prescription drug given to children with ADHD (Attention Deficit Hyperactivity Disorder) to help them focus in their studies. It is completely safe if taken in moderation.
