Common questions

Where can I find historical IB Physics SL grade boundaries?

This page lists every published IB Physics SL boundary across recent exam sessions, with timezone variants where they apply, plus a graph that traces each grade cutoff over time.

What if a boundary is missing for IB Physics SL?

If the IBO has not released boundaries for a given session, the table omits that row. The graph reuses any earlier session that does have a published boundary so trends remain visible.

Are these IB Physics SL boundaries official?

The numbers are taken from official IB grade boundary documents. They are reproduced here for reference and do not modify the published cutoffs.
