MAY VS NOVEMBER IB RESULTS: A DATA-LED SESSION COMPARISON
May is much larger; November can shorten a recovery timeline. Neither fact chooses a session for you. The useful question is whether a session fits your subjects, school access, preparation window and admissions deadline.
Side-by-side, without turning averages into promises
Across 2023, 2024 and 2025, the May session had roughly nine times as many students as November. May also reported a higher Diploma Programme pass rate and mean total points. These are stable descriptive differences in the displayed period, but they do not isolate the effect of the month. The bulletins cover different cohorts, subject mixes and candidate histories.
For retake planning, volume matters indirectly. A larger session may align with more school calendars and subject offerings. A smaller session may still be the best option when it prevents a full-year delay. Availability must be confirmed locally rather than inferred from the global totals.
| Measure | May 2023–2025 | November 2023–2025 | Responsible reading |
|---|---|---|---|
| Average students | 191,630 | 21,693 | Shows scale, not the number of retake candidates. |
| Average DP pass rate | 80.8% | 73.3% | Describes cohorts; not a forecast for one student. |
| Average mean points | 30.38 | 29.23 | Useful context, not a target-setting rule. |
| Countries in latest year | 153 | 134 | Global reach does not guarantee local subject availability. |
Choose a session with a constraint matrix
A candidate normally has several constraints that are more decisive than the global pass rate. Put them in one matrix and mark each as confirmed, uncertain or unavailable. This prevents a plan from resting on an assumption such as ‘November is offered near me’ or ‘the university will wait for May results.’
The most important inputs are the registration route, subject and level, exam location, preparation time, university deadline and fallback. A decision is robust when it still works if one uncertain input turns negative.
| Constraint | May question | November question | Evidence to collect |
|---|---|---|---|
| Host school | Can it register an external or former candidate? | Does it participate in November? | Written coordinator confirmation |
| Subject | Is the exact subject and level available? | Is the exact subject and level available? | Registration subject list |
| Preparation | Would the longer/shorter runway improve readiness? | Can a focused plan be completed in time? | Diagnostic papers and weekly hours |
| Admissions | Will results meet the institution’s timeline? | Would November preserve the next intake? | Written university guidance |
| Fallback | What happens if the grade is unchanged? | What happens if the grade is unchanged? | Alternative offer or later session plan |
Planning errors the bulletin cannot solve
The practical rule. Choose the earliest session that is actually available and leaves enough time to produce a measurable improvement—not simply the session with the better aggregate statistics.
- Choosing the statistically higher-pass-rate session before confirming a registering school.
- Assuming every subject is available in every session or location.
- Treating mean total points as a grade boundary or university requirement.
- Building a plan around an expected improvement without a diagnostic baseline.
- Ignoring the result-release date and the university’s document-processing time.
- Using a global country count as evidence that a nearby school accepts external candidates.
