Introduction
Choosing your Higher Level (HL) subjects in the IB can feel overwhelming. It’s not just about picking what you like—your choices affect your daily workload, university prospects, and future career. So if you’ve ever wondered, “How do I choose my HL subjects wisely?”—this article will give you everything you need to decide confidently.
What Are HL Subjects in the IB?
HL subjects are IB courses taught in greater depth and over a longer period—typically 240 teaching hours compared to 150 for Standard Level (SL). HL courses demand more essays, more advanced content, and higher expectations.
You'll usually pick 3 HL subjects, though some students choose 4 (more on that later).
How HL Subjects Affect University Admissions
Many universities look closely at your HL subjects, especially for subject-specific degrees. For example:
- Engineering applicants often need HL Math and HL Physics
- Medical schools prefer HL Chemistry and/or HL Biology
- Business programs may expect HL Math or HL Economics
In competitive university systems (like the UK), failing to meet HL prerequisites can get your application rejected—even with a strong total score.
Knowing Yourself: Strengths vs. Interests
Before you pick your HLs, ask:
- What subjects do I enjoy?
- Where do I naturally excel?
- What subjects can I stay motivated in—even when it's hard?
Don’t pick HL Chemistry just because it looks good if you struggle to pass tests. The goal is to challenge yourself—not sabotage your GPA.
Researching Career and University Pathways
Look up degree requirements on official university websites. Use platforms like:
- UCAS (UK)
- CollegeBoard or individual college sites (US)
- Studielink (Netherlands)
- Ontario Universities Info (Canada)
Check for subject prerequisites and preferred HLs. Then build backwards.
The Balance Between HL and SL
You want HLs that stretch you—but don’t forget that SL subjects still matter. Choose a mix that’s:
- Academically rigorous
- Sustainable with your extracurriculars, EE, CAS, and TOK
An ideal mix is 2 HLs that you love and 1 that’s useful or strategic.
Which Subjects Are Commonly Chosen at HL?
Some of the most frequently chosen HLs include:
- HL English A
- HL Economics
- HL Biology
- HL Chemistry
- HL History
- HL Mathematics AA
But don’t choose a subject just because it’s popular. Fit matters more than trend.
What to Avoid When Picking HL Subjects
- Peer pressure: Your friends’ subjects are not your roadmap.
- Guessing what looks impressive: HL Philosophy isn’t better than HL Psychology unless it fits your goals.
- Ignoring future plans: Choosing HLs without considering university implications can backfire.
Pros and Cons of Each Group 1–6 at HL
Group 1 (Language A)
- Develops analytical skills and essay writing
– Heavy reading and interpretation load
Group 2 (Language B or Ab Initio)
- Good for bilinguals and global degrees
– HL Literature B is demanding for non-native speakers
Group 3 (Individuals and Societies)
- Great for social sciences, law, business
– Some topics can be dense (e.g., global politics, history)
Group 4 (Sciences)
- Essential for medicine, engineering, etc.
– High IA workload and content depth
Group 5 (Maths)
- HL is required for STEM degrees
– HL Analysis is intense—don’t underestimate
Group 6 (Arts)
- Excellent for creative students
– Often overlooked, but strong for design/media paths
When to Choose Math HL or SL
Choose Math HL if you’re going into:
- Engineering
- Computer Science
- Physics
- Economics (some universities require it)
Math SL or Math AI is better if:
- You’re pursuing arts, humanities, or law
- You want to manage workload and still meet requirements
Language HL Considerations
Pick HL for a language if you:
- Are fluent or near-native
- Love literary analysis
- Can handle lengthy comparative essays
Otherwise, SL might provide a better balance.
HL Science Subjects: What to Know
HL sciences mean:
- Longer labs and more lab reports
- Advanced topics (e.g., organic chemistry)
- High pressure if you’re also doing EE in a science
Only commit if you’re strong in these areas and enjoy applied learning.
How Many HLs Should You Choose?
Stick with three HLs unless:
- You’re genuinely passionate and capable
- Your university target requires 4 HLs
- You have a strong support system
Four HLs add pressure—rarely improve your profile unless truly strategic.
Sample Subject Combinations Based on Degree Goals
Medicine: HL Chemistry, HL Biology, HL Math AA
Engineering: HL Math AA, HL Physics, HL Chemistry
Law: HL English A, HL History, HL Global Politics
Business: HL Economics, HL Math AI/AA, HL Language
Psychology: HL Psychology, HL Biology, HL English A
Humanities: HL History, HL English A, HL Language B
The Role of Teacher Advice in HL Selection
Before you finalize your HL subjects, talk to:
- Your current subject teachers
- Your IB coordinator
- University admissions reps if possible
Ask about your readiness, potential, and the depth of HL curriculum.
