Just use some following tips
Create mental images: Visualise in your memory an image of something or someone you want to remember.

Make new connections: Making new connections is the process which relates new information to what you already know thereby making the new information easier to recall.
Grouping: Sorting and grouping are ways of categorising data to provide memory traces to aid in recall. Relationships among major groups and among the items in each subgroup create the connections which make all items memorable.
Repetition: Repetition helps you hold information in your short-term memory as your working memory organises and integrates it into long-term memory.Memory aids: Memory aids are concrete reminders - notes, calendars, pill safes - which help you remember.
