Test anxiety is a huge problem for all ages, but especially for high school students (SATs) and college students (mid-terms and finals). The most popular method for preparing for these challenges is cramming. Imagine that your head is a large paper bag and that the subject matter you need to learn is groceries. Your goal is to try to get as many groceries as possible into your bag without ripping the bag wide open (also known as "cerebral meltdown"). From the looks on the faces of those entering SAT test centers around the world at the crack of dawn, it's easy to see a lot of heavily damaged brain bags. Shouldn't there be a better way?
Well, German researchers (the same Einsteins that brought you the Volkswagen windshield defroster) have discovered that the best way to keep those groceries in your bag is to grab a quick nap after your cram-shopping session. In my non-scientific opinion, this would seem to make sense because you would give your brain a chance to put all your groceries neatly away in your cupboards and refrigerator (also known as unconscious cerebral processing). But, hey, what do I know?
