Query: Memory technics made practical

Dave Farrow's book/ course Memory Mastermind makes use of old techniques in a novel manner. The technology of images which is the basis of the programme has been available for a while, but that which makes this course relevant and useful is the applications. He combines image technology with 'mind and confidence boosting' techniques and plain common sense to produce a motivational course helpful to anyone who wishes to remember any material whatsoever.The course is worthwhile to anyone who has never read or researched anything about memory techniques and who would like to improve his/her memory. It will certainly aid and increase retention and the capacity to study. In will also provide useful tips to anyone who does have a grounded knowledge of memory techniques.I found the course to be fun and enjoyable. Though the organization of the tapes could be better, the exercises are kept short and sweet and you can work through at your own time and at your own pace.
