Mind mapping is a great way to organize your thoughts visually. There are digital tools you can use (check out this list of 5) but it's usually more effective to create one on paper by hand. They can be used for:
Studying: Map a textbook chapter or lecture notes to better understand, remember, and make connections
Writing Papers: Map out your thoughts to generate a topic or thesis question, outline your supporting research, and find connections to help you with transitions
Presentations: Present information visually, so that the audience can see how your ideas are organized and connected
