The best subjects for law in the IB are usually English A, History, Global Politics, Philosophy, Economics, and a language, particularly when one or two are taken at Higher Level. However, most undergraduate law courses do not require a particular IB subject, and there is no IB Law course that applicants are expected to study. Your strongest combination is therefore one that develops sustained reading, evidence-based argument, precise writing, and critical evaluation while allowing you to achieve competitive grades.
Requirements vary by university, course, country, and application year. Before finalizing your subjects, check every course you may apply to rather than relying on a general list of recommended humanities.
Do universities require particular IB subjects for law?
For standard UK undergraduate law degrees, specific subjects are uncommon requirements. Cambridge states that it does not ask for any specific subjects for Law, while Oxford says that an essay subject is helpful but not required. UCL similarly lists no specific subjects for its LLB, although applicants must meet its broader academic subject expectations.
This distinction matters:
- A required subject must be taken for your application to be eligible.
- A recommended or helpful subject may prepare you well but is not compulsory.
- A preferred subject list may affect whether the overall combination is considered sufficiently academic.
- A grade requirement specifies the total IB score, HL results, or individual subject grades expected.
Current published examples illustrate the range. For 2027 entry, Cambridge lists 41-42 points with 776 at HL, while Oxford lists 38 points including core points, with 666 at HL. UCL's published 2026 LLB requirement is 39 points with 19 across three HL subjects and no HL score below 5. These figures are examples, not universal law thresholds, and may change for later cycles.
Some specialized courses create exceptions. Oxford's Law with Law Studies in Europe expects the relevant language for certain European-language options. Universities may also impose separate English-language or mathematics requirements, so a lack of law-specific prerequisites does not mean there are no entry conditions.
The strongest IB subjects for law
No subject guarantees admission. The useful question is which combination best develops the academic abilities assessed in a law degree.
| IB subject | Preparation it provides | Important limitation |
|---|---|---|
| English A: Literature or Language and Literature | Close reading, interpretation, concise analysis, and structured essays | Literary analysis is not the same as legal analysis, although many skills transfer |
| History | Source evaluation, contextual reasoning, evidence selection, and competing interpretations | Content volume can be substantial, especially at HL |
| Global Politics | Power, sovereignty, rights, institutions, and contemporary case studies | It does not teach domestic legal doctrine or qualify as prior legal study |
| Philosophy | Logic, definitions, counterarguments, assumptions, and ethical reasoning | Abstract argument can be demanding if you prefer concrete case studies |
| Economics | Policy evaluation, incentives, regulation, and quantitative interpretation | Some students find its models less useful for developing extended prose than History or English |
| Language B or another Language A | Precision, communication, cultural awareness, and access to international opportunities | A language may become essential for a degree containing study in that language |
| Mathematics or a science | Logical discipline, careful use of evidence, and analytical problem-solving | These subjects are valuable but do not replace regular practice in extended writing |
English A
English A at HL is one of the clearest ways to demonstrate advanced reading and writing. Law students must identify how wording affects meaning, distinguish a central claim from supporting material, and communicate conclusions precisely. Both Literature and Language and Literature can develop these abilities, so choose according to your strengths and the courses available at your school.
The RevisionDojo English A Language and Literature resources include Paper 1, Paper 2, oral, and HL essay support. The separate English A Literature resource hub is more appropriate if you study Literature.
History
History is excellent preparation because it requires arguments based on incomplete or contested evidence. You learn to assess provenance, compare interpretations, establish causation, and decide which evidence deserves the greatest weight. These habits resemble legal reasoning, even though historical and legal methods are not identical.
History HL is not automatically the best choice for everyone. If its workload would significantly reduce your overall diploma score, another essay-based subject in which you are stronger may be more sensible. Students taking History can use IB History notes, questions, and essay practice to work on evidence-led responses.
Global Politics, Philosophy, and Economics
Global Politics introduces concepts closely connected to public and international law, including sovereignty, legitimacy, rights, conflict, and international institutions. Its case-study approach can help students connect abstract principles to real disputes. The IB Global Politics resource collection supports both conceptual understanding and assessment preparation.
Philosophy trains you to test definitions, expose assumptions, and respond fairly to counterarguments. Economics is especially relevant to competition law, taxation, regulation, corporate activity, and public policy. Neither is inherently better for admission, so the decision should reflect your interests, likely grade, and preferred type of reasoning.
Recommended HL combinations
A strong law-oriented programme normally includes at least one essay-intensive HL subject. Two can provide even better preparation, but only if the workload remains manageable.
Possible combinations include:
- English A HL, History HL, Global Politics HL for intensive reading, argument, and public affairs.
- English A HL, History HL, Economics HL for a balance of textual, historical, and policy analysis.
- History HL, Economics HL, Language B HL for international, commercial, or comparative interests.
- English A HL, Philosophy HL, Mathematics HL for argument, logic, and broad academic range.
- History HL, Chemistry HL, Mathematics HL for students keeping both law and STEM options open.
These are examples rather than prescribed combinations. Three highly demanding essay subjects can create overlapping deadlines, while a law-oriented combination that excludes sciences may close routes such as medicine or engineering. RevisionDojo's guidance on choosing IB HL subjects can help you compare preparation, performance, and workload rather than selecting subjects by reputation.
How IB Diploma rules affect your choices
Under the official Diploma Programme structure, students study six subjects alongside Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service. Students normally select subjects across the six groups, but the arts subject can be replaced by an additional language, individuals and societies subject, or science. The IB requires a minimum of three and a maximum of four HL subjects, with the remaining subjects taken at SL.
HL courses have a recommended 240 teaching hours, compared with 150 hours at SL. Consequently, taking four HLs is not automatically more impressive and can reduce the time available for coursework, admissions tests, and the core. The RevisionDojo explanation of IB subject numbers clarifies the programme structure, while its Group 3 subject comparison can help with humanities choices.
Subject choice depends on where you want to study
United Kingdom
Law is commonly studied as a first undergraduate degree, usually an LLB or, at some universities, a BA in Law or Jurisprudence. Selective universities often emphasize high overall and HL grades rather than one mandatory school subject.
Some universities require the Law National Aptitude Test, or LNAT. The LNAT does not test legal knowledge. It contains a multiple-choice section based on argumentative passages and an essay section, assessing comprehension, reasoning, and written argument. Cambridge, Oxford, LSE, and UCL are among the institutions currently requiring it, but applicants must check the official list and each university's deadline for their cycle.
United States
In the United States, the JD is generally a postgraduate professional degree, so students first complete an undergraduate degree. The American Bar Association does not recommend a single undergraduate major or prescribed pre-law course sequence. IB subjects therefore affect admission to your bachelor's programme rather than direct entry to law school, and a broad combination can preserve more undergraduate options.
Australia and other systems
Australia offers direct-entry undergraduate law programmes, but requirements differ significantly. For example, the University of Queensland currently specifies an English prerequisite for its Bachelor of Laws (Honours), while other institutions may focus primarily on an overall admission rank or IB score. Combined law degrees may also require prerequisites belonging to the second discipline.
Civil-law jurisdictions, bilingual programmes, and courses involving a year abroad may place greater importance on languages. Always check the exact degree rather than assuming that one university's conditions apply throughout a country.
How to make the final decision
Use the following order when selecting your IB programme:
- List realistic university courses and countries. Include ambitious, competitive, and safer options.
- Record official requirements. Note total points, HL grades, required subjects, English conditions, admissions tests, and deadlines.
- Choose at least one strong essay subject. English A, History, Global Politics, or Philosophy are common options.
- Protect your grades. A fashionable combination is unhelpful if it produces weaker results than subjects suited to your abilities.
- Keep alternatives open. If you are uncertain between law and a prerequisite-heavy field, preserve the subjects needed for that alternative.
- Confirm school availability. Not every IB World School teaches every subject or permits every timetable combination.
The Extended Essay can also strengthen relevant skills, but it does not need to concern law. A well-executed investigation in History, English, Economics, Philosophy, or another approved subject can demonstrate independent research more effectively than a forced legal topic outside your course knowledge.
Common mistakes to avoid
- Assuming you must study Law before university.
- Selecting three essay-heavy HLs without considering workload or likely grades.
- Treating Global Politics as a substitute for learning legal doctrine.
- Choosing Mathematics at a particular level based on rumor rather than course requirements.
- Ignoring language prerequisites for bilingual or European law programmes.
- Checking a university's total IB score but missing its separate HL, English, or admissions-test conditions.
- Preparing for the LNAT by memorizing legal facts, even though it tests aptitude rather than legal knowledge.
Conclusion
The strongest subjects for law are those that build close reading, analytical writing, evidence evaluation, and disciplined argument. English A, History, Global Politics, Philosophy, Economics, and languages are particularly useful, but most standard law degrees do not prescribe one ideal combination. Prioritize verified entry requirements, strong grades, and at least one subject involving substantial argument-based writing.
RevisionDojo can support this preparation through its complete IB subject resource library, including Study Notes, Questionbank practice, Flashcards, and Jojo AI feedback. Use the subject-specific resources most relevant to your combination, especially timed essay practice for English, History, and Global Politics.
