Study in increments

Cramming the night before a test isnt just stressful; its ineffective. Our brains arent meant to absorb and retain information [that we] reviewed at the last minute, Dietzel said. Thats because repetition is key to learning, and last minute stress can lead to anxiety that blocks our ability to readily understand and recall information. Instead, Dietzel suggests starting a week ahead and studying in 15 to 20 minute increments.
