Deciding on your IB subject combination is more than a ticklist; choosing your subjects can shape your academic path and affect your university choices. If you want to be a doctor and lab scientist, lawyer, engineer, or math, find the combo that works to help you gain a competitive advantage.
For Future Doctors:
Best HL Subjects:
- Biology HL
- Chemistry HL
- Mathematics AA SL or HL (for more competitive programs)
Recommended SL Subjects:
- English
- Psychology or another science (Physics/ESS)
- Second Language
Why These?
Around the world, medical programs are looking for a solid foundation in the sciences—especially Chemistry and Biology. Math provides analytical rigor and background knowledge of statistics, and Psychology can provide insight into the complexities of patient behavior.
For Aspiring Lawyers:
Best HL Subjects:
- English A HL
- History HL or Global Politics HL
- Economics HL or another humanity
Recommended SL Subjects:
- Second Language
- Mathematics AI SL
- Science (any)
Why These?
Law requires strong analytical, reading, writing, and argumentative skills. As no one subject indicates a commitment to law, students should seek to show their ability to think critically and write research-based essays. History and Global Politics allow students to do both of these things.
For Future Engineers:
Best HL Subjects:
- Mathematics AA HL
- Physics HL
- Chemistry HL (optional but useful for some fields)
Recommended SL Subjects:
- English
- Second Language
- Computer Science (if available)
Why These?
Top engineering programs prioritize Math and Physics, especially at HL. Chemistry is crucial for chemical or biomedical engineering. Some universities may even require Math HL specifically.
Some final considerations for IB Subject Selection:
- Balance passion with practicality: It is important to choose subjects you enjoy and will enjoy studying, along with having enough IB subjects that align with university-prerequisite requirements.
- Find out if the university is subject-specific with requirements, which is important, especially in the UK, Canada, and the EU, where entrance requirements are very rigid.
- Do not overcommit and take extra higher-level subjects: Three higher levels are sufficient if you demonstrate strengths across subjects.
