Why doesn't cramming work?

Answer 1

Trying to stay up all night and cram for a test doesn't work for many reasons:

• you'll be tired the next day, and tired brains don't think as well as rested brains
• you go over the material so much that you're tired of seeing it, and tired brains don't work as well as fresh brains
• by waiting until the last minute, you miss a lot of the information that you could have learned little by little
