This is a mind map generator you can use to create mind maps and then organize them.
You can arrange your notes, or you can brainstorm your ideas, or you may create a timeline and add in relevant information that you need to memorize.
If you know how to use them correctly, mind maps can be a great tool.
If you are not aware how mind maps work, then you should really learn about them so you may use them when you are revising.
Good luck with your finals!
