In the math IA, there are two main deadlines: the first draft submission and the final draft submission. In fact, there is a separate deadline for the teacher for official submission to IBO, and there are cases where teachers allow extra time to adjust your IA before the official submission even after the final draft submission. Shoutout to all teachers who do this (you guys are the true heroes), but this is usually the exception rather than the norm. Hence, you should always try to submit your final draft on time. Nevertheless, when all else fails and things do not work out as planned, we have no choice but to ask for a deadline extension.
