To remember 3 words in a cognitive test, repeat them right away to make sure you heard them. Then link the words into a simple story or picture in your mind. For example, if the words are apple, penny, and table, imagine an apple sitting on a penny on a table. Repeat the story quietly to yourself a few times and stay relaxed. During the test, go through the story again when asked to recall. This method uses visualisation and repetition, which help short-term memory. Practice can make it easier too.
