Instead of completing a pre-written problem, the difficulty arises from the need to conceptualize a unique mathematical inquiry. Therefore, the first step is to deconstruct the process by selecting a subject that truly interests you. The most difficult parts of your write-up should therefore be addressed early in your study sessions using the Hardest-First Technique for IB Study. In order to get beyond writer's block, it's also important to look at examples and see how other people organized their projects.
