IB Psychology HL - 2027 - Questionbank

Content All - Biological Approach

This feature allows you to complete original Paper 1 questions at any point, drawing only on the content and contexts you have already covered. When you are ready, you can tackle full Paper 1s covering all areas of the course.  There are two types of Paper 3 investigations available. First, there are modified Paper 3 investigations, which are skills-focused tasks designed to build and develop specific abilities in data analysis and interpretation. There are also Full Paper 3s, which have the same format, structure and timing as the IB Paper 3 exam.

Here you will find original Paper 3 investigations and topic-specific Paper 1 IB exams. When you are ready, there are also full Paper 1s, covering all areas of the course. 

HL - 2027

In the Specimen Papers section, you will find full worked solutions to the questions on the IB Psychology HL (Higher Level) Specimen Papers for the 2027 exams. Within each video, an experienced IB teacher will guide you through the solution, step-by-step. Past paper solutions from previous years are not published here, as the question types and exam format differ significantly from the newly updated course.

Full worked video solutions for all 2027 specimen papers, taught by experienced IB instructors.
