Memory
Developing your memory is a skill like any other, and will improve the more you practice. There are several methods to go about doing this.
1) Practice as many of the tests as possible on this web site to become familiar with the methods used during the real exam.
2) Practice reading passages and pictures in newspapers and magazines. Focus on names, and test yourself 30 minutes later to see how you did.
3) Have a friend note the makes, colors, and licence plates of a few cars in an area and test yourself 30 minutes later.
4) Form pictures or links in your mind to assist your memory. For example if you see a mug shot of a person that reminds you of your friend; link that friend to the mug shot to memorize it. Here is an example to assist you with licence plates.
954 PNY - remember 954 People in New York
651 ZTZ - remember 651 Zee TeaZe (the tease)
421 PLM - remember 421 PLuMber
Do whatever works for you. (Psychologists have found that by making expressions graphic, people remember them more easily.)
Observation
The goal of this exercise is to test your observation capabilities. When comparing the faces, focus on features that will not change (assume there is no plastic surgery involved.) Focus on the shapes of the eyes, the size and appearance of the nose and the shape of the face. Ignore features that can be altered easily such as hairstyle, facial hair, clothing, glasses, etc.
Tips to improve your observation skills include:
1) Practice as many of the exams as possible on this web site to become familiar with the testing process.
2) Purchase "spot the difference" puzzles.
3) Do word find puzzles in local papers.
