The PEG system allows you to remember sequences of ten unrelated items in the appropriate order. In using the method of loci, visualize a room or route that is familiar to you. This is especially helpful in giving speeches or having to remember lists of important points in a correct sequence. For example, if you wish to memorize the presidents of the United States in order, you might deposit a dramatic image of each president in strategic location around your house. Remember that mnemonic devices increase your ability to recall information.
Mnemonics also have certain drawbacks.
They do not help you to understand the material, they can be time consuming to learn, and under stress you may forget the mnemonic, therefore, being unable to retrieve the information you need.
