A mind map is made by writing down a main idea and then coming up with new ideas that are related to the main idea. By focusing on key ideas written in your own words and finding connections between them, you can map knowledge to understand better and retain it.

MindMeister is an online collaborative, knowledge-based mind-mapping tool that students can use to understand and make connections between concepts, ideas, and information. Mind maps help users collect ideas and facts based on a given topic.
