I see nothing wrong with combining mental. I start back at uni next week and since I have the photoreading personal learning course and Kevin Trudeau's mega memory I think that a good combination for presentations would be to photoread and activate the materials, mind map them and then use mega memory and turn the key words on my mind map into pictures and then commit them to memory. That way I could give my presentation wothout using notes. Does anyone have any thoughts on this?
