ExploreAbout this exam
IB Philosophy Higher Level is the two-year Diploma Programme course in philosophy, assessed by the IB Organisation and graded on the 1–7 scale. It suits students who enjoy argument more than memorisation: you are asked to reconstruct positions, expose assumptions and defend your own view in continuous prose. The course pairs a compulsory core theme, Being human, with one or more optional themes chosen by your school - typically from aesthetics, epistemology, ethics, philosophy and contemporary society, philosophy of religion, and philosophy of science - and a prescribed text studied in depth. Higher Level candidates also sit a separate paper requiring close philosophical analysis of an unseen passage, and complete an internal assessment analysing a non-philosophical stimulus such as an advertisement, film or news item. Preparation is reading-and-writing heavy: learn each named philosopher's core claims and the standard objections to them, practise timed essays on past paper questions, and build a personal bank of examples. Teachers select the optional themes and prescribed text, so confirm your school's choices before revising.

What you'll study
About IB Philosophy HL preparation
What does the exam actually look like?
Three external papers plus internal assessment. Paper 1 responds to an unseen stimulus text and links it to the core theme; Paper 2 consists of essays on your studied optional themes; Paper 3, HL only, analyses a philosophical passage. Your teacher marks the internal assessment, which is externally moderated. Confirm paper structure with your teacher, as the IB publishes current specifications.
How many questions and how long is each paper?
The IB Organisation publishes the current paper structure, question counts and time allocations in its official subject guide and assessment materials. These are revised periodically, so check the IB website or ask your coordinator for the figures applying to your session rather than relying on second-hand summaries.
How hard is HL Philosophy compared with Standard Level?
The content overlaps, but HL adds Paper 3 and expects greater depth: more primary-text engagement, finer distinctions and more sustained argument. Students who find essay writing slow often find the workload heavier than the philosophy itself. Strong candidates read the prescribed text directly rather than relying on summaries.
Can I retake the exam?
Retake arrangements, including whether you may carry over internal assessment marks, are set by the IB Organisation and vary by session and category. Ask your school's DP coordinator, who handles registration and can confirm the current rules and deadlines for your circumstances.
Which optional themes should I choose?
Usually your school decides, not you. If there is a choice, pick the theme whose primary texts you will genuinely read: epistemology and philosophy of religion reward careful reading, while ethics and contemporary society reward wide real-world examples. Ask early, because switching themes mid-course is costly.
What order should I study in?
Start with the core theme, Being human, since Paper 1 depends on it and its concepts recur elsewhere. Then begin the prescribed text early so you can revisit it. Layer in optional themes, and practise Paper 3-style passage analysis throughout rather than cramming it at the end.
What are the most common ways candidates lose marks?
Describing philosophers' views without arguing; ignoring the exact wording of the question; failing to use the stimulus text in Paper 1; and asserting objections without explaining them. Unsupported assertions and unstructured essays also cost marks. In the internal assessment, a weak choice of stimulus or a merely descriptive treatment is a frequent problem.
How should I prepare in the final months?
Write timed essays under exam conditions and get feedback on structure, not just content. Build a one-page map per philosopher: core claims, key distinctions, standard objections and your own response. Practise extracting the argument from unseen passages. Re-read the prescribed text rather than only your notes on it.
