Education

Want to get smarter? Run more. At least, that's what recent studies have found. Running stimulates the brain to grow new neurons / grey matter in the hippocampus. This is the part of the brain used for contextual memories (both in time and space), and is critical for "fluid intelligence" (our ability to reason and problem-solve). In fact, going for an AM run improves blood flow to the brain, as well as relieve stress and anxiety... a good way to start any test. That and sleeping, breathing, meditating, eating complex carbohydrates, and laying off the drugs also help.

Don't fret if you're injured and can't run. Any form of aerobic exercise improves intelligence (so long as you're not studying while you doing it... dang it... the only way I could stay awake while reading text books was on an exercise bike). Yoga also has beneficial effects, although weight lifting doesn't.
