Choosing your IB subjects is a critical decision, and if you're considering a future in science, you might be wondering—who should take IB Biology? The answer depends on your interests, career goals, and academic strengths. This comprehensive guide explores who benefits most from taking IB Biology, whether at Standard Level (SL) or Higher Level (HL), and why it could be a smart choice for your IB Diploma Programme.
1. Aspiring Doctors, Nurses, and Health Professionals
If you're aiming for a career in medicine, healthcare, or biomedical sciences, IB Biology is often either a prerequisite or a highly recommended subject. Many prestigious universities—such as the University of Toronto and Western University—expect applicants for programs like medicine, pharmacy, or neuroscience to have taken IB Biology at either SL or HL.
Why it helps:
- Covers human physiology, genetics, and immunity
- Aligns with university-level pre-med content
- Builds scientific vocabulary and lab experience early
2. Future Biologists, Ecologists, and Environmental Scientists
IB Biology isn't just about humans. The course dives deep into ecosystems, evolution, biodiversity, and cellular processes—all of which are foundational for students interested in life sciences, environmental science, veterinary science, and more.
Why it helps:
- Prepares you for courses in ecology, botany, zoology, and agriculture
- Includes data analysis and evaluation of environmental impact
- Cultivates systems thinking and research skills
3. Students Who Love Experiments and Scientific Investigation
IB Biology is not a purely theoretical course. It includes a rich array of practical lab work, field investigations, and research projects. If you enjoy exploring questions hands-on and discovering science through experimentation, this course is a perfect fit.
Why it helps:
- Develops investigative skills through internal assessments
- Encourages collaboration in group projects
- Teaches data collection, statistical analysis, and experimental design
4. Learners Seeking to Strengthen Critical Thinking and Reasoning
Scientific literacy isn’t just about facts—it’s about understanding how we know what we know. IB Biology emphasizes the nature of science, helping students develop the ability to evaluate evidence, challenge assumptions, and recognize the limitations of scientific knowledge.
Why it helps:
- Promotes evidence-based thinking
- Builds argumentation and critical analysis
- Useful in debates, policy-making, and ethical reasoning
5. Students Who Want to Pair Biology with Chemistry or Physics
IB Biology naturally complements other science and math subjects. Whether you're pairing it with Chemistry for a future in biochemistry or with Math for data-heavy biology courses, the synergy strengthens your overall IB portfolio.
Why it helps:
- Fulfills the Group 4 (Sciences) requirement
- Creates cross-disciplinary learning opportunities
- Enhances lab and problem-solving skills
6. Candidates Ready for a Challenging and Rewarding Curriculum
IB Biology at HL is known for its depth, academic rigor, and comprehensive scope. It covers additional topics and more demanding content compared to SL, making it ideal for highly motivated students with strong science aptitude.
Key differences:
Level: SL (Standard Level)
- Study Hours: 150
- Depth & Breadth: Covers core concepts and basic practicals
Level: HL (Higher Level)
- Study Hours: 240
- Depth & Breadth: Includes additional topics, deeper analysis, and extended practical work
7. Students Targeting Science and Health Degrees Worldwide
Universities around the world—including those in Canada, the UK, Australia, and the U.S.—look favorably upon IB Biology for admissions into science, health, agriculture, and forensics programs.
Examples:
- University of Manchester: Requires HL Biology for BSc Biology programs
- Western University: Accepts SL or HL Biology for Medical Sciences
- McGill and U of T: Expect science prerequisites for science streams

FAQs About Who Should Take IB Biology
Q1: Can I take IB Biology without taking Chemistry?
A: Yes, but many students take both for a stronger science foundation, especially if applying to medical programs.
Q2: Is HL Biology too difficult for average students?
A: It’s challenging but manageable with consistent effort. If you're passionate about science and stay organized, you can succeed.
Q3: Does IB Biology help with non-science careers?
A: Yes—it builds analytical thinking, writing, and data interpretation skills valuable in any field.
Q4: Is there a lot of memorization in IB Biology?
A: Yes, but it's balanced with application, evaluation, and critical thinking. It’s not just about recall.
Q5: How do I decide between HL and SL?
A: Choose HL if you want to study science at university or love biology. Choose SL if you want exposure but need to balance your workload.
Final Thoughts: Is IB Biology Right for You?
If you're intrigued by how living systems work, enjoy scientific exploration, or have future plans in science, medicine, or health, IB Biology is a strong and strategic choice. Whether you're aiming for a top university or simply love the life sciences, the course offers skills and knowledge that go far beyond the classroom.
Before you commit, think about your long-term goals, your interest in science, and your willingness to commit to a course that’s both demanding and deeply rewarding.
