strategies for testing
When we move around from place to place while studying, we form associations between the material and the new environment, making the memory stronger.
Quizzing yourself will not only help prepare you for the real deal, but lets you know what you need to focus on and what you've got down.
talk it out
When you read the information out loud, you're mentally storing it in two ways: seeing & hearing, allowing you to cause stronger associations and therefore stronger memory.
Set a reward for completing the next three pages of notes, or for getting through the next 20 minutes without procrastinating. Food, getting on your phone, or just getting up and walking around the block - whatever will motivate you.
get some caffeine
Lots of research has shown that caffeine makes us more alert, focused, and therefore on task.
