IB Psychology HL Notes

Aimnova offers free IB Psychology HL revision notes covering the same three approaches, research methodology and four contexts as SL, plus the HL extension — culture, motivation and technology — and the HL-only Paper 3 source-based data-analysis paper. Each topic includes clear explanations, worked diagrams, spaced-repetition flashcards, and IB-style practice questions with AI feedback — no sign-up required to read the notes.

IB Psychology is a way of thinking, not a list of studies. The course and every markscheme reward explaining a mechanism or theory clearly and then evaluating it through the six concepts — bias, causality, change, measurement, perspective and responsibility. These notes model that method throughout, so you learn to argue about behaviour rather than just describe an experiment.

The notes are organised by unit and topic according to the official IB syllabus, so you can revise systematically for Paper 1 (short-answer questions, a scenario application, and a concept essay, 35%), Paper 2 (your own practical plus an unseen-study essay, 25%), Paper 3 (the HL-only source-based data-analysis paper, 20%), and the Internal Assessment (a hypothetical research proposal, 20%). The Paper 3 skill — interpreting data, weighing credibility, bias and transferability, and treating correlation as distinct from causation — is built in alongside the Paper 1 and Paper 2 technique.
