There are many ways to make studying fun. For one, you can reward yourself every time you attain a study goal. Did you memorize all of your biology notecards? Time for a slice of pizza. Did you finally hammer down that complicated math equation? Call your friend to talk about it and celebrate.
Probably the most fun way to study is by forming a study group with your friends and classmates. You can bounce ideas off each other and help each other better understand concepts. But be warned: This can be a double-edged sword. If your group doesn’t create a focused and concrete plan for the study session beforehand, you may end up procrastinating more than studying.
