Plan your storyboard first. Usually a storyboard is accompanied by pictures, but with the IELTS examination, you will use only words. Create a beginning, middle and end to your story in the form of an outline.
Monitor your time. You have 60 minutes to complete the writing portion of the IELTS examination. If it takes you 15 minutes to outline the story, you will have 45 minutes left. Continue tracking your time to be sure that you have adequate time to finish the storyboard.
Break down your story outline into scenes. A storyboard consists of individual scenes with characters who come together to form a complete story --- much like a comic strip.
Add descriptions to each scene you mapped out, using brief captions to focus on the action taking place. For example, you might have a male character who enters a room angrily and throws down a bag.
Incorporate dialogue. Storyboards often include simple dialogue that helps to advance the story. In the example above, the male character might state: "I am never riding the subway again!" The female character in the room might react calmly, while continuing to file her nails, murmuring: "You say that every Friday."
Bring the story together. Before you run out of time for the IELTS examination, you must conclude the story. The above scene might climax with the male character attempting to take a cab home from work and being met with even more challenges than when he was taking the subway. The story might resolve with the character entering his home angrily, exclaiming: "I am never taking a cab again!" Part of your score on the writing examination is dependent on whether or not you can create a story that has a clear beginning, middle and ending --- including a climax and resolution.
