Physics Exemplars

About Physics Coursework Exemplars

The Coursework Exemplars section gives IB students (both SL and HL) access to real, high-quality samples of IB Physics Internal Assessments (IA) and Extended Essays (EE). Each exemplar is carefully selected to model top-scoring work, aligned with IB assessment rubrics and showcasing what examiners expect at different achievement levels.

On this page, you'll find full-length exemplars annotated with examiner commentary, highlighting strengths, weaknesses, and specific rubric-based insights. These samples demonstrate how ideas are structured, arguments developed, and criteria met to achieve high marks.

Every exemplar is enriched with Jojo AI
