Honesty is always the best policy: completing your IA on time will actually save you from the headache of deadline negotiations and deception. However, if you identify as a morally grey character and are out of options for any further extensions,there is one final resolution you may use: submit a corrupt file. The trick is that your teacher will think you submitted your IA on time, but they cannot open the file due to a technological issue, and you will earn extra time to finish your IA until the “technological issue” is solved. You can use an online service to corrupt your file: https://corrupt-a-file.net/.
Many teachers may already be aware of this trick, as they may have used it themselves when they were students (even teachers procrastinate!). Also, this should be used to grant yourself an extension for the first draft submission (the IB final submission deadline is non-negotiable).
Conclusion
The concepts introduced here provide a brief preview/sneak peek into the high scoring math IA topics that some of our past students have successfully written. Taking the ideas in this document at face value and straight up copying the formulas/derivations/graphs will not guarantee a high score. The concepts are to be used as a benchmark guide / reference / playbook that will set a standard on the complexity/depth/breadth of IA topics. If you truly want a 7 (or 18/20 and above), you must dedicate sufficient time and effort to understand your topic inside and out, then customize the investigation with elements that evidently reflect your own academic interests.
Take inspiration from the high level concepts and techniques from each topic and let it serve as a rough framework. The specific data gathering, modeling, context and scope definition should vary according to standards personally tailored to your own goals, interests, and academic needs.
