One of the most common questions IB students ask is deceptively simple:
When do IB May 2026 exams actually start?
The confusion usually comes from:
- Different subjects starting on different days
- Morning vs afternoon sessions
- School calendars not matching the IB timetable
Understanding the exact IB May 2026 exam start date is critical, because it determines how you pace your revision, manage early stress, and avoid burning out before the most difficult weeks.
This guide explains:
- The official IB exam start date for May 2026
- Which subjects begin first
- Why not all students start exams on the same day
- How to plan revision properly using the official timetable
Official IB May 2026 Exam Start Date

According to the official IB examination schedule, IB May 2026 exams begin in late April.
However, this does not mean:
- Every student has an exam on the first day
- All subjects begin simultaneously
- The first week is low-pressure
The IB staggers exams deliberately to manage global participation and subject clashes.
