When doing the key points on the mind map, kind of do them in a PEE (point, evidence, explain) format. For example (even though you may not eb doing Christianity as one of your topics):
Creation story helps Catholics understand nature of God as shows God created world and helps them understand the omnipotent nature of God -> "In the beginning God created the heavens and the earth" (genesis 1:1)
you can make it more concise that that but that was a rough example, as the example boards just want to see how you explain and provide evidence for your points so make all your notes in a short PEE format as if your answering a question, in a way.
Also, revise your RS exam boards mark scheme on past papers and how they say you should answer it as you can apply that criteria to other questions
