Questions

What is an IB grade boundary?

It is the lowest overall percentage of the total marks that earns a given grade. Each sitting the IB adds up a student's marks across all components, then compares the percentage with that sitting's cut-offs for grades 1 to 7. Anything at or above the grade 7 line is a 7.

Why do the boundaries differ between timezones?

The IB sets different papers for different regions so that exams are not sat at the same hour worldwide. Two papers are never exactly equal in difficulty, so the cut-offs are set per paper set. When one timezone is harder, its boundaries come down. TZ0 means the sitting had one set of papers for everyone.

Are May and November boundaries comparable?

Only loosely. May is the large sitting, taken by most schools in the northern hemisphere and many elsewhere. November has fewer, differently prepared students, and some courses are not offered in it. Compare May with May when you track a trend.

How can I use boundaries to set a target?

Pick the grade you want, then read its percentage across the last few sittings and use the highest as a safe target. Add a margin of a few points, because the line moves each year. Then check your practice papers against that percentage, not against a single paper's raw mark.

When are the next boundaries published?

The May 2026 boundaries are in the tables above. November 2026 boundaries normally appear with the results in early January 2027, and the next May sitting's in early July 2027. This page is updated when each set is released.
