The outline method is a pretty straight-forward method of note taking in class. Check out the video below for a good idea of how this works.
You may also choose to use this method just to review for a test or quiz.
To do a mind-mapping method of note-taking, you're using a visual method, which may be great for some learners.
You can also find templates to use on a website like Canva to help you. See the video below for an example of how this works.
Typically, students do this after class to organize notes or show how information is connected. Students don't usually do mind map notes during class.

Updated and revised edition As every student quickly learns, merely sitting through a class and paying attention is usually not sufficient to ensure good grades. The proper taking of good notes is essential. Note-Taking Made Easy tells why the student should take his or her own notes (rather than buying them or taping lectures), and tells exactly how to determine what is worth noting, whether during a lecture, classroom discussion, even from a book or during a meeting. The authors describe the two most successful methods of organizing notes—outlining and patterning—and provide shortcuts to really make note-taking easy, from shorthand devices to abbreviations. Special sections are devoted to taking notes from texts, fiction as well as nonfiction, and handling charts, graphs, and photos. A final chapter shows how to tie together notes from various sources. This STUDY SMART reference guide series, designed for students from junior high school through lifelong learning programs, teaches skills for research and note-taking, presents strategies for test-taking and studying, provides exercises to improve spelling, grammar, and vocabulary, and reveals secrets for putting these skills together in great essays.
