3. Tips for IA in Group 3 Subjects

3.1 Check the Criteria Carefully for Differences by Level

As you might have noticed, there are differences in weightings and contents between HL and SL for some Group 3 subjects. Especially HL students in Business and Global Politics need to be careful because there are additional tasks for them in  IA.

But, as long as you check the criteria as you go through your IA project, there’s nothing to be worried about because the criteria give you a very specific outline. So make sure you read it carefully at least once, highlight the important parts, and follow the guidelines step by step.



3.2 Use Figures and Tables to Save Word Count

As you can see in the table for IA overview, all subjects have a word limit. To save words for important parts like discussion and analysis, it’s best to use figures and tables where appropriate such as in the methodology and results and findings. There’s nothing harder than having to cut sentences you already wrote to fit into the word limit. When using figures and tables, make sure to put a correct title and annotation when necessary.



3.3 Try to Have Multiple Perspectives

What makes writing IA in group 3 subjects more difficult than in other subjects is the importance of having strong arguments from multiple perspectives, which is also the reason why you should make your RQ (Research Question) an open-ended question rather than just a yes-no question (e.g starting with “To what extent” or “How” instead of “Do/Does”). You also need to give depth into your arguments so there will be a lot of research involved in the process, but make sure to choose appropriate research methods from your course.
